Port the mingw shared-build machinery: MSYS2 0009/0010 + the dynload_win cluster (0011-0015) + 0018 + 0034 + 0066 + 0039; the smoke leg goes --enable-shared

The wall (tebako-runtime-python PR #16, run 34735362057, leg
windows/3.14.7): the full factory build reaches the extension modules
and dies linking Modules/array.cpython-314.so — undefined references
to PyExc_EOFError/_Py_Dealloc/PyUnicode_* and the rest of the core
API. On PE/Windows a loadable module cannot carry undefined symbols at
link time, and statically embedding the core per-extension breaks
interpreter-state identity — the --disable-shared + .so extensions
shape is impossible by construction on Windows. The intended shape is
--enable-shared (the factory's PythonVersion#msys_dll_name and
upload_release dll-facet path were written for it; the ruby factory
ships that way).

Eight MSYS2 MINGW-packages ports close it, inserted in series order:

- 0009 -> exports_declspec_msys (verbatim): HAVE_DECLSPEC_DLL on
  __MINGW32__ + the cygwin arms (auto-import functions, dllimport
  data, exported PyMODINIT_FUNC). Without it the core exports nothing
  in the MSVC style and the import library binds no API surface.
  Inert for the static build: the special-linkage block still gates on
  defined(Py_ENABLE_SHARED) || defined(__CYGWIN__).
- 0010 -> configure_shared_mingw_msys, with ONE hunk elided (the
  closing LIBS hunk — one carrier for -lversion/-lshlwapi/-lpathcch/
  -lbcrypt, the syslibs deviation's post-MODLIBS SYSLIBS position; a
  pre-MODLIBS LIBS copy of -lbcrypt would not resolve libcrypto's
  static refs). The ported hunks: the enable_shared MINGW arms
  (LDLIBRARY=libpython$(LDVERSION).dll.a, DLLLIBRARY=
  libpython$(LDVERSION).dll — the factory's msys_dll_name —,
  BLDLIBRARY=-L. -lpython$(LDVERSION)), the static LDLIBRARY=.a arm,
  LDSHARED/LDCXXSHARED=$(CC) -shared -Wl,--enable-auto-image-base, and
  LIBPYTHON/MODULE_DEPS_SHARED for win32 — what puts $(BLDLIBRARY) on
  every stdlib extension link and $(LDLIBRARY) on its dependency list.

The 0009+0010 cross proof then exposed the wall cascade; each further
port is forced by named evidence (local cross build,
x86_64-w64-mingw32-gcc 14 on macOS, configure --host=
x86_64-w64-mingw32 --enable-shared):

1. The libpython3.14.dll link died: Modules/getpath.o references
   PyWin_DLLhModule (Modules/getpath.c:811-816, compiled only under
   Py_ENABLE_SHARED && MS_WINDOWS — the static tree never misses it),
   and upstream defines the symbol only in PC/dl_nt.c, which the
   autoconf build never compiles. 0012 (dynload_win_msys, verbatim)
   cures it: DYNLOADFILE=dynload_win.o plus PC/dl_nt.o in
   extra_machdep_objs. The loader switch is itself forced — base mingw
   has no dlopen (configure falls to dynload_stub.o = a shared build
   that cannot load anything; the v0.3.2 skip note's "ucrt64 has
   dlfcn" was wrong).
2. 0012 drags its coherence cluster, previously deferred as interop
   naming: the dynload_win.o compile rule passes
   -DPYD_PLATFORM_TAG='"$(PYD_PLATFORM_TAG)"' (0011), and
   dynload_win's import filetab is .pyd-based
   (Include/internal/pycore_importdl.h, upstream), so the build-time
   suffix must agree — 0013 (SHLIB_SUFFIX=.pyd + the import-lib
   install rule) and 0014 (mingw SOABI=cp<ver><thread>-
   <PYD_PLATFORM_TAG>, EXT_SUFFIX=.<SOABI>.pyd). Observable rename:
   windows-msys extension modules change spelling from
   .cpython-314.so to .cp314-mingw_x86_64_ucrt_gnu.pyd. And dl_nt.c's
   PyWin_DLLVersionString = MS_DLL_ID needs 0015's definition
   (MS_DLL_ID via CFLAGS_NODIST; upstream defines it only in the MSVC
   pyconfig).
3. dynload_win.c then failed to COMPILE: its static _Py_CheckPython3
   collides with pylifecycle.h's external declaration under
   MS_WINDOWS. 0066 (verbatim) drops the declaration; no other caller
   exists.
4. python.exe then failed to link: Programs/python.c provides wmain
   under MS_WINDOWS, and linking wmain needs -municode — without it
   the mingw CRT pulls the WinMain startup (crtexewin) and dies
   (crtexewin.c:62: undefined reference to `WinMain'). 0039 (one
   anchor elided — its closing configure.ac hunk rides on 0010's
   elided LIBS case; the FIELD3/RCFLAGS additions apply verbatim in a
   fresh mingw case at the same spot) rewrites the interpreter link
   with -municode + the python_exe.o version/icon resource, adds
   pythonw.exe (-municode -mwindows, the GUI variant every windows
   install ships), the DLL's python_nt.o version resource, the
   windres/RCFLAGS configure machinery, and the altbininstall
   python3w.exe lines.

This PR's own CI then exposed the next wall (run 34741183330, leg
smoke 3.14.7 (windows-msys)): with the link shape fixed, every make
target died at frozen-module regen — ModuleNotFoundError: No module
named 'winreg' / Fatal Python error: _PyImport_InitExternal: external
importer setup failed (Makefile:1957/1960, frozen_modules/abc.h,
codecs.h). Root cause: Lib/importlib/_bootstrap_external.py:36 imports
winreg at module top level whenever sys.platform == 'win32', and the
autoconf build never builds winreg (upstream compiles it MSVC-only via
PCbuild) — so EVERY mingw interpreter boot dies in import setup,
_bootstrap_python included. 0018 (winreg_modules_msys, verbatim +
regen) cures it: winreg/msvcrt/_winapi become bootstrap-static modules
(Setup.bootstrap.in + PY_STDLIB_MOD), winsound gains -lwinmm and
_overlapped -lws2_32 (Setup.stdlib.in), crtdbg.h is debug-gated in
_winapi.c/msvcrtmodule.c, and dynamic_annotations.c's _MSC_VER guard
becomes MS_WINDOWS.

The second CI leg then moved one step deeper (run 34742370411, job
103684133612): with winreg in place the interpreter boots past
_PyImport_InitExternal and dies at Lib/site.py:330 — _get_path's win32
branch (sys.platform == 'win32' via configure_machdep_msys) reads
sys.winver -> AttributeError: module 'sys' has no attribute 'winver'
(Makefile:1964/1967, the same frozen-headers regen). Upstream
sysmodule.c installs winver/dllhandle only under MS_COREDLL, an
MSVC-project-only macro (PC/pyconfig.h) the autotools build never
defines — while the definitions it guards DO exist in this link (0012
compiles PC/dl_nt.o, 0015 defines MS_DLL_ID). 0034
(sysmodule_coredll_msys — the transformation verbatim, the hunks
re-authored against 3.14.7: the upstream hunk-3 context rides MSYS2's
own 0003 sys._is_mingw_ucrt patch, which this series does not carry)
makes the guard defined(MS_WINDOWS) && defined(Py_ENABLE_SHARED); in
the static shape the guard stays false (static behavior unchanged),
POSIX untouched, no configure.ac change so no regen.

Deliberately skipped from the cluster's neighborhood (recorded in the
PR body): 0067 (PYTHONLEGACYWINDOWSDLLLOADING — uninstalled-tree test
convenience; its mingw_smoketests.py hunk targets an MSYS2-CI-local
file), 0068 (GetPythonImport libpython-name port — without it the
wrong-python-version guard is inert, not broken: the .pyd imports
libpython3.14.dll, which never matches the MSVC "python" prefix),
0069 (backslash normalization — its precondition is MSYS2-fork
forward-slash path handling this series does not carry), 0070
(suppress the python3.dll preload under mingw — with PY3_DLLNAME=
libpython3.14.dll the preload resolves to the already-loaded core DLL,
a harmless no-op; its hunk context also rides on the skipped 0067).

tools/compile_smoke follows the factory's new linkage shape (the
coverage contract — the smoke IS the factory's shape): the windows-msys
leg configures --enable-shared and gains the one LINK regression
target — Modules/array$(EXT_SUFFIX), the exact run-34735362057
casualty, never probed, EXT_SUFFIX read off the generated Makefile (it
now resolves to the .pyd spelling). The POSIX leg is untouched
(pristine tree, upstream's static default, 12 wall TUs).

Verified locally (macOS + homebrew mingw-w64 gcc 14; the native ucrt64
build is CI's oracle): the 35-patch series applies clean to pristine
3.14.7 (tools/lint) — the 34-patch prefix reproduces the reference
tree byte-for-byte, and 0034's only target (Python/sysmodule.c) is
touched by no other entry; shipped configure/pyconfig.h.in equal the
pinned autoconf 2.72 regen exactly; rspec 103/0; validate_manifests
OK; the POSIX smoke leg compiles all 12 wall TUs on the pristine tree.
Cross proof: configure yields the MSYS2 spellings (LDLIBRARY=
libpython3.14.dll.a, DLLLIBRARY=libpython3.14.dll, DYNLOADFILE=
dynload_win.o, MACHDEP_OBJS=PC/dl_nt.o, SHLIB_SUFFIX=.pyd,
EXT_SUFFIX=.cp314-mingw_x86_64_ucrt_gnu.pyd, PY_ENABLE_SHARED=1); the
build links libpython3.14.dll (38 MB), python.exe, pythonw.exe, and
Modules/array.cp314-mingw_x86_64_ucrt_gnu.pyd — the
run-34735362057 casualty under its new name; the DLL export table
carries PyExc_EOFError/_Py_Dealloc/PyUnicode_FromString (the wall's
undefined symbols) among 3678 exports; the .pyd imports
libpython3.14.dll; the DLL's own imports add libgcc_s_seh-1.dll and
libwinpthread-1.dll — the two mingw runtime DLLs the factory's windows
layout must stage beside the exe. The 0018 shape: winreg/msvcrt/
_winapi compile into the core archive (PC/winreg.o,
PC/msvcrtmodule.o, Modules/_winapi.o), the generated Modules/config.c
registers all three in _PyImport_Inittab, and PyInit_winreg exports
from the DLL. The 0034 shape: Python/sysmodule.o compiles for the
target and the python.exe link still closes. Both boot-time fixes are
provable only at run time — the CI smoke leg is the oracle.
