Celia Chen de83e7674a Instrument MCP OAuth credential store locks (#61430) ...

## What changed

- Record acquisition counts, wait durations, and hold durations for file and secrets store locks, tagged by store, lock mode, operation, and originating client. Acquisition metrics also report outcome and contention.
- Preserve the resolved credential store's originating client across storage operations and lock release, and exclude nonblocking probes from lock metrics.
- Add `record_global_duration` for standalone durations with the existing buffering limits and metrics opt-out behavior.

## Testing

Extend tests to verify lock metrics for shared and exclusive access, contention, timeouts, probe exclusion, and originating-client attribution. Add coverage for standalone duration buffering, validation, and opt-out behavior.
