d3d12: Remove keyed mutex support 

Keyed mutex support was deprecated and the only known client using it,
Chromium, has migrated to fences. Remove all related keyed mutex related
code and tests. The useFenceSynchronization field is still present in
the external image descriptor since it's set by Chromium (to true) -
it'll be removed once Chromium stops setting it.

Bug: dawn:1612
