We need to pack special AFBC-specific plane descriptors instead of the generic

Row stride is defined in terms of header blocks for AFBC. Usually,
afbc.row_stride is used for AFBC images and row_stride for non-AFBC images;
however, the nonsense non-AFBC stride leaked into the UABI. So handle that in
the legacy conversion path and use a unified row stride (equal to
afbc.row_stride for AFBC images and row_stride otherwise).

Midgard has multiple Surface Descriptor formats selectable in the texture
descriptor. Previously, we have used both the "64-bit surface descriptor" and
the "64-bit surface descriptor with 32-bit line stride and 32-bit layer stride".
A delicate routine tried to guess what stride the hardware will use if we don't
specify it explicitly, and omit the stride if it matches. Unfortunately, that
routine is broken in at least two ways:
* Textures with ASTC must always specify an explicit stride. Failing to do so
(like we were doing) is invalid.
* It applies even for interleaved textures. The comment above the function
saying otherwise is incorrect. (TODO: double check this)
Bifrost onwards always specify the strides explicitly. Let's just do that and
unify the gens. What is lost from doing this? A ludicrously trivial amount of
memory and texture descriptor cache space. 8 bytes per layer*level per texture,
in fact. Compared to the size of the textures being addressed, the memory usage
is trivial. The texture descriptor cache size maybe matters more. But given
Arm's hardware people went this direction for Bifrost and stuck to it, I doubt
it matters much.

Before we used GenXML, pan_texture mixed layout code with texture descriptor
packing code. For the most part, the layout code is generation-independent; the
pack code is not. We introduced an anti-pattern where the file was compiled N+1
times: N times for each PAN_ARCH value, and an extra time with no PAN_ARCH
value. And then the contents of the file changed completely depending on
PAN_ARCH. This is a pretty weird construction.
Let's instead split off the layout file from the descriptor file, compile the
layout file once, and compile the descriptor file per-gen.

It's too complicated and probably for no actual benefit. The main reason
we have BGR formats is for display, but that's export and doesn't get
hit by this path. Internal BGRA textures are possible with a Mesa

possible optimization. My apologies, and thanks for the fish.

Imported resources will not necessarily have their line stride aligned

Gallium wants the depth or stencil component replicated on all .XYZW.
That's easily done on pre-v7 since we can forge all the swizzles we
want, but Bifrost v7 only supports a few combinations, so we have to
combine the user swizzle with our own 'replicate' swizzle to make it
work. Note that v7 has a trick to make border color work when the GRBA
order is chosen: they apply the red border color to the green component.
