vkd3d: Use atomic exchange for descriptor writes.
The descriptor component of struct d3d12_desc is replaced with a union containing a pointer which can be swapped out using InterlockedExchangePointer(). To make it safe to increment the refcount of such an object it is necessary to cache freed objects. Elimination of the descriptor mutexes on games which use multithreaded descriptor writes nearly doubles framerate on recent hardware.
