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 release. 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.
