Validate shader interface compatibility #1923

Closed doitsujin closed 4 months ago

doitsujin commented 4 months ago

At PSO compile time, the D3D12 runtime validates the input layout against the VS input signature, as well as the interface between each connected shader stage. This can fix some cases of invalid Vulkan usage as well if games rely on runtime validation to catch these mismatches.

Also fixes some small vkd3d-shader issues I've encountered in the process.

Draft because this needs more real-world testing to ensure we don't break existing games somehow.
