vkd3d-shader: Introduce DESCRIPTOR_INFO_FLAG_UAV_ATOMICS and always declare UAV images with known type for atomic ops.

Browse Source 
Atomic ops on images with Unknown type will cause SPIR-V validation failure,
and assertion failure in Mesa debug builds. D3D12 allows atomics on typed
buffers, and this requires a distinction to be made between UAV reads and
atomic ops.
