kept byte_code as a 'DWORD *'. Alternative: use 'uint32_t *' instead, but would require larger changes:
- internally in wined3d
- requiring also to typecast from 'DWORD *' (the type in D3D* interfaces), to 'uint32_t*' (to be decided where: either is every client, or inside wined3d)
Ideally we'd change these anyway, but since the ultimate plan is to move these all to vkd3d-shader, it doesn't really matter.
- kept state_id as DWORD (ditto previous commits)
Ideally we'd also change this anyway, but I think we want to get rid of the state table completely, so I guess this is fine as a temporary measure.
