vkd3d: Use Vulkan null descriptors if EXT_robustness2 is available.

This implements all remaining unsupported image view dimensions and saves
a small amount of resources because null buffers and images are no longer
needed. It matches the D3D12 requirement that all reads return zero,
which is not strictly true of the existing implementation using resources
of small but non-zero size. Warnings on null view creation are silenced
because there should no longer be a difference from D3D12 behaviour.
