vkd3d-shader/hlsl: Express deref->offset in whole registers.

Browse Source 
This is required to use SM4 relative addressing, because it is limited
to whole-register granularity.

* This offset is stored using two fields, one for a variable part and other for a constant
* part, which are added together:
* - offset: An offset given by an instruction node, in number of register components.
* - offset: An offset given by an instruction node, in whole registers.
* - const_offset: A constant number of register components.
* Since the type information cannot longer be retrieved from the offset alone, the type is
* stored in the data_type field, which remains NULL if the deref hasn't been lowered yet. */
