vkd3d: Re-implement d3d12_command_list_ClearUnorderedAccessViewUint().

Browse Source 
Addresses the following limitations of the previous implementation:
    - Only R32_{UINT,TYPELESS} were supported for buffers.
    - Clearing an image UAV did not behave correctly for images with non-UINT formats.
    - Due to the use of transfer operations, extra memory barriers were needed.

If necessary, this will create a temporary view with a bit-compatible
UINT format for the resource in order to perform a bit-exact clear.
