util/format: Use correct pipe format for VK_FORMAT_G8_B8_R8_3PLANE_420_UNORM.

NV12 is UVUVUV (https://wiki.videolan.org/YUV#NV12) and in Vulkan is
VK_FORMAT_G8_B8R8_2PLANE_420_UNORM. So U=B and V=R. So plane order in

layer by the x86_test-gl/vk images (meaning the former only needs to be
downloaded once for either or both of the latter). This should be more
efficient in terms of overall network bandwidth and storage, in
particular if the base image changes less often than the -gl/vk ones.

intel/fs: Remove min_dispatch_width spilling decision from RA

Move the decision one level up, let brw_compile_*() functions use the
spilling information to decide whether or not a certain width
compilation can spill (passed via run_*() functions).

The min_dispatch_width was used to compare with the dispatch_width and
decide whether "a previous shader is already available, so don't
accept spill".

This is replaced by:

- Not calling run_*() functions if it is know beforehand a smaller width
  already spilled -- since the larger width will spill and fail;

- Explicitly passing whether or not a shader is allowed to spill.  For
  the cases where the smaller width is available and haven't spilled,
  the larger width will be compiled but is only useful if it won't
  spill.

Moving the decision to this level will be useful later for variable
group size, which is a case where we want all the widths to be allowed
to spill.
