radv: Set the RADEON_SURF_OPTIMIZE_FOR_SPACE flag for images
This looks like a regression from df301237940 ("radv: use
ac_compute_surface"). Before that, the opt4Space addrlib flag was set
to true unless the image has FMASK (ac_compute_surface will similarly
only set that flag for images without FMASK).
This saves multiple gigabytes of VRAM on one of our games, and brings
its VRAM utilisation on RADV in line with AMDGPU-PRO and NVIDIA.
