When doing fast clear for single-sample color buffers for the first time,
a CMASK buffer has to be allocated and the CMASK state in all pipe_surfaces

This looks like r600g. The shared Cayman MSAA code is used here.

The real motivation for this is that I need the ability to change values
of color registers after the framebuffer state is set. The PM4 state cannot
be modified easily after it's generated. With this, I can just change

meta: Support GenerateMipmaps on 1DArray textures.

I don't know how many people care about this case, but it's easy enough
to do, so we may as well.  The tricky part is that for some reason Mesa
stores the number of array slices in Height, not Depth.

I thought the easiest way to handle that here was to make Height = 1
(the actual height), and srcDepth = srcImage->Height.  This requires
some munging when calling _mesa_prepare_mipmap_level, so I created a
wrapper that sorts it out for us.

meta: Support GenerateMipmaps on 2DArray textures.

This is largely a matter of looping over the number of slices/layers,
and not minifying depth (presumably that code exists for the unfinished
3D texture support).

Normally, I would have made the loop over array slices the outermost
loop.  I suspect that would make it trickier to support 3D textures
someday, though, so I didn't.  The advantage is that we would only have
one BufferData call per slice, rather than one per miplevel and slice.

However, a GenerateMipmaps microbenchmark indicates that either way is
basically just as fast.  So I'm not sure it's worth bothering.

Improves performance in a GenerateMipmaps microbenchmark by nearly 5x.
