vkd3d-shader/hlsl: Allow derefs to provide the data_type.

Browse Source 
After lowering the derefs path to a single offset node, there was no way
of knowing the type of the referenced part of the variable. This little
modification allows to avoid having to pass the data type everywhere and
it is required for supporting instructions that reference objects
components within struct types.

Since deref->data_type allows us to retrieve the type of the deref,
deref->offset_regset is no longer necessary.
