  -----------
  [Darwin][TSan] Use deadlock detector aware calls for Darwin-specific lock interceptors (#216040)

Currently the deadlock detector is unaware of these lock types because
the interceptors use bare Acquire-Release calls. This patch switches
them over to the Mutex(Pre|Post)Lock calls instead.
