vkd3d: Make all descriptor reads and writes atomic.
Shadow of the Tomb Raider overwrites descriptors while they are being copied in another thread. This patch makes reads and writes atomic for CBV, SRV, UAV, and sampler descriptors, but not RTV and DSV, for which copying is not implemented.
Benchmark total frames vs mutex count (the single mutex was locked only once for copying):
1 mutex: 6480 6489 6503 8 mutexes: 6691 6693 6661 16 mutexes: 6665 6682 6703
