intel/fs: switch scratch surfaces to surface state heap

Lionel Landwerlin requested to merge llandwerlin/mesa:review/intel-fs-scratch-fix-gfx125 into main

In 4ceaed78 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).

We have to make this configurable as Iris uses the bindless heap for scratch.
