jif 421082e79d Avoid blocking async proxy resolution on the system proxy cache (#47852) ...

## Why

Platform proxy resolution holds the system proxy cache mutex, so checking the cache could block a Tokio worker while another lookup was in progress.

## What changed

Use `try_lock` for cache reads, treating contention as a cache miss so async callers on Windows and macOS wait through the existing asynchronous resolver path.

## Testing

Add a Windows/macOS regression test that verifies resolution yields while the cache is locked and completes after release. Adapt the cached-route test to tolerate concurrent cache writers, and isolate the unavailable-decision cache test from shared cache contention.
