In DXBC tessellator parameters are specified in hull shaders. In OpenGL,
even in SPIR-V, tessellator parameters must be specified in the
tessellation evaluation shader.

We would like to allow building libvkd3d-shader as a standalone library
without our Direct3D translation layers.
In the long term, it should be possible to build and use libvkd3d-shader
without Win32 data types, Vulkan headers and libs.

Vulkan has different descriptor types for buffers and textures.
Therefore, we do not know the exact Vulkan descriptor type for D3D12 SRV
and UAV descriptors up front. This information can be extracted from
shaders when creating PSOs but creating incompatible Vulkan descriptor
set layouts for PSOs with the same root signature would introduce a lot
of complexity.
In order to preserve compatibility between resource bindings for PSOs
with the same root signature we duplicate Vulkan descriptors for SRVs
and UAVs (a buffer view and an image view descriptor). This strategy may
be reasonable for small root signatures.
