[libcxx] Don't hold the lock when calling notify_* on gates in std::shared_mutex (#107876)

Holding the associated lock while calling notify_* on a
condition_variable is generally considered a pessimization, as the
notified thread might "instantly" wake up, notice that it can't acquire
the lock, and then goes back to sleep.
