[msan] Stop calling pthread_getspecific in signal handlers.
pthread_getspecific is not async-signal-safe.
MsanThread pointer is now stored in a TLS variable, and the TSD slot
is used only for its destructor, and never from a signal handler.
This should fix intermittent CHECK failures in MsanTSDSet.
