runtime: add race annotations to metricsSema

metricsSema protects the metrics map. The map implementation is race
instrumented regardless of which package is it called from.

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

See similar instrumentation on trace.shutdownSema and reflectOffs.lock.

Fixes #53542.
