vkd3d-shader/hlsl: Store hull and domain shader properties in vsir_program.

Browse Source 
The alternative to adding the vsir_program->tess_output_primitive and
vsir_program->tess_partitioning fields would be to emit the vsir
DCL_TESSELLATOR_OUTPUT_PRIMITIVE and DCL_TESSELLATOR_PARTITIONING
instructions, like DXIL does, but I think that the preference is to store
these kind of data directly in the vsir_program.
