intel/fs: put scratch surface in the surface state heap

In 4ceaed7839af we made scratch surface state allocations part of the
internal heap (mapped to STATE_BASE_ADDRESS::SurfaceStateBaseAddress)
so that it doesn't uses slots in the application's expected 1M
descriptors (especially with vkd3d-proton).

But all our compiler code relies on BSS
(STATE_BASE_ADDRESS::BindlessSurfaceStateBaseAddress).

The additional issue is that there is only 26bits of surface offset
available in CS instruction (CFE_STATE, 3DSTATE_VS, etc...) for
scratch surfaces. So we need the drivers to put the scratch surfaces
in the first chunk of STATE_BASE_ADDRESS::SurfaceStateBaseAddress
(hence all the driver changes).
