TPF validation

Vkd3d-shader generally assumes that Direct3D shader bytecode is valid and doesn't do much validation. We should introduce some kind of validation pass. The validation potentially could be optional, e.g. used only in debug builds.

  • Interpolation mode is the same for all variables in the input register.
  • Number of indices for resources (SM5 vs SM5.1).

Vulkan

  • Try to fix detached WSI surfaces after D3D9/D3D11 swapchain (OpenGL) is created for a window with D3D12 swapchain (Vulkan).
  • Fix child window rendering for D3D12 RenderDoc.
