vkd3d-shader/hlsl: Handle HLSL_CLASS_VECTOR in hlsl_regset_index_from_deref().

Browse Source 
Loads of components of vectors (i.e. functionally a subset of SWIZZLE
instructions, but expressed using LOAD) are legal, and generated elsewhere.
Due to circumstances they never reach this point currently, but we shouldn't use
vkd3d_unreachable() here.
