radv: prepare fmask surface creation

The old code copied over all the surface info from the image
surface, we only want some bits of it, and to modify the flags.

This prevents a regression in dEQP-VK.api.copy_and_blit.resolve_image.*
and others in the subsequent switch to ac_compute_surface.

v2:
- also disable opt4Space in radv_amdgpu_surface, so that we can
  apply this patch separately *before* switching to ac_compute_surface
  and hopefully avoid intermittent regressions (Nicolai)
