This changes the locking behaviour for IPC port mutexes in TSAN builds to use a single shared mutex for all ports, rather than individual mutexes per-port. This avoids the need to potentially lock a large number of mutexes simultaneously when sending a large number of ports in an IPC message. I've tried to leave in the various debug assertions such that it still acts like there are multiple mutexes under the hood. It is likely that this could harm performance somewhat due to the increased contention, however it should have no impact on actual release builds.
