Some of these may need additional work to work for real, but we should
be able to support them.
We also include some formats that are not supported for images, but
that we want to support for buffers, such as R32G32B32 for a vertex
buffer. In the future we might want to expand the format table to
specify which formats are supported for buffers.

This ignores stencil for now and focuses on depth testing without
support for early depth testing.
To implement this we need to start considering how many of our
framebuffer attachments are color attachments, since some of the
computations we use to determine tile sizes and binning configuration
depend on this.

This relies heavily in infrastructure taken from the v3d driver. We should
probably look for ways to share the code between both drivers by creating
a surface layout library that we can use from both, or at least moving
parts of the v3d driver to broadcom/common. Specifically:
We take v3d_tiling.c, which requires gallium's pipe_box type for some
helper functions that we don't quite need yet.
We copied and adapted bits of v3d_resource.c into v3dv_image.c, however,
it should be possible to look for ways to reuse the code instead of
duplicating it.
Pre-compute UIF padding into the slice setup. This is different from
what we do in v3d (we do this at cerate_surface time), but it is
more convenient for us to pre-calculate it here for all mipmap
slices.

This takes a subset of vk_format_info.h from Anvil which has some
Intel specific elements. At some point we might want to discuss
if we want to make the file reusable and move the intel bits to
some other place, but it is not a lot of code and for now this works,
so we keep going.
