Add `PowerWriteACValueIndex` stub.
This is required for an internal application to work
It seems like the status-quo is just leaking the outputs of `debugstr_guid`, so I did that....

Unlike previous vkd3d-utils interfaces, ID3D12ShaderReflection is rather more
large and complex, and will probably end up needing several new individual
scan interfaces from vkd3d-shader, which are themselves not exactly trivial to
design.
Therefore, instead of implementing everything in vkd3d-shader and then hooking
up the vkd3d-utils interfaces on top of that, this patch series copies the
existing implementation of reflection and then begins the process of moving its
implementation to vkd3d-shader.
The primary motivation here is to add reflection crosstests (primarily for the
benefit of the HLSL compiler) without being blocked on API design. Part 2 of
this patch series does this.
