[TRITON] Add gluon support for MXFP4 quant kernel in gfx950 and gfx1250

[NimitPtl]

Motivation
Using gluon instead of triton for performance improvement

Technical Details
Gluon kernel, with sizes derived from the TTGIR of Triton kernel.

Test Plan
Test suite as well as benchmark script for testing accuracy and speed of quant kernel.

Test Result
Marginal improvement for gfx950 and around 50% improvement with usage of LDS in gfx1250

M             N                     (Bandwidth (GB/s))

Gluon 4096.0 8192.0 0.001115
Triton 4096.0 8192.0 0.002147

🏷️ CI Guide

Runs automatically on every PR:

• ✅ Pre-checks (submodule verification, code formatting)
• ✅ Aiter op tests (gfx942 + gfx950)
• ✅ Triton tests on MI35X (only when aiter/ops/triton/** or related paths are changed)

Extended tests (opt-in via labels):

Label	Tests
ci:triton-300x	Run an additional Triton test job on MI300X in PRs; main branch always runs both MI35X and MI300X
ci:sglang	SGLang integration tests: DeepSeek-R1-MXFP4 accuracy, Qwen 3.5 accuracy
ci:atom	ATOM benchmark: DeepSeek-R1-0528, GPT-OSS-120B
ci:atom_full	ATOM accuracy suite for PR and main models from ATOM models_accuracy.json
ci:vllm	vLLM benchmark: GPT-OSS-120B, DeepSeek-R1-0528, Kimi-K2.5
ci:all	All standard extended tests (excludes ci:atom_full)

Only add ci:atom_full for FlyDSL or Triton upgrades.
