Add compute provider validation to worker deployment version summary (#810)

**What changed?**
Added `ComputeStatus` to the Worker Deployment API with a
`ProviderValidationStatus` that tracks the result of the most recent
connectivity check between Temporal and a customer's compute resource.
An empty error message means validation passed; a non-empty message
describes what failed.

**Why?**
Enables surfacing the connectivity health between Temporal and a
customer's compute resource (e.g. Lambda) through the Worker Deployment
API, so the UI can show ongoing validations status of compute configs
without additional queries.

**Breaking changes**
None. All additions are new optional fields; existing clients are
unaffected.
