  Log Message:
  -----------
  [libcxxabi] Make InitByteGlobalMutex check GetThreadID instead of PlatformThreadID

By relying on PlatformSupportsThreadID, InitByteGlobalMutex disregards
the GetThreadID template argument, rendering it useless.

This is the 2nd of 5 changes to overhaul cxa_guard.
See D108343 for what the final result will be.

Depends on D109539
