runtime: add race annotations to cbs.lock

cbs.lock protects a map. The map implementation is race instrumented
regardless of which package is it called from.

lock/unlock are not automatically race instrumented, so we can trigger
race false positives without manually annotating our lock acquire and

compileCallback is used during initialization before the P is available,
at which point raceacquire will crash during a racecallback to get the
race proc. Thus we skip instrumentation until scheduler initialization
is complete.

Fixes #50249.
