Damien Carver d22fde239d Bug 2051928 - Reduce Rust marker recording lock contention with a read-fast/write-slow tag lookup r=canova,profiler-reviewers

get_or_insert_deserializer_tag took a process-global exclusive write lock on
every marker, serializing all Rust marker recording across threads. Take a
shared read lock for the already-registered steady state and only escalate to
the exclusive write lock (with a double-checked re-lookup) on first
registration of a marker type.
