vkd3d-shader/hlsl: Calculate the bind count from the vector width.

Scalars have a reg_size of 4 on sm1. In the case of a deref of a vector or
matrix resulting in a scalar, however, this yields a required_bind_count that is
one higher than it should be. reg_size is the wrong thing to be using here,
since it describes the size of a type in isolation, but this is conceptually an
embedded type that doesn't include any padding. Since we're only dealing with
scalars and vectors here, just use their width.

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

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.
