The DRI interface for modifiers with aux data treats the aux data as a
separate plane of the main surface.
When the dri layer requests the plane associated with the aux data, we
save the required information into the dri aux plane image.
Later when the image is used, the dri plane image will be available in
the pipe_resource structure's `next` field. Therefore in iris, we
reconstruct the aux setup from this separate dri plane image when the
image is used.

Reworks:
* If the aux-state is not ISL_AUX_STATE_AUX_INVALID, then use memset
even when memset_value is zero. The hiz buffer initial aux-state
will be set to invalid, and therefore we can skip the memset. But,
for CCS it will be set to ISL_AUX_STATE_PASS_THROUGH, and therefore
the aux data must be cleared to 0 with the memset. Previously we
would use BO_ALLOC_ZEROED with the CCS aux data, so this memset
wasn't required. Now, the CCS aux data may be part of the main
surface. We prefer to not use BO_ALLOC_ZEROED excessively, so the
memset is needed for the CCS case. (Nanley)

This is not currently required because the hiz buffer is in a separate
buffer, and therefore the offset is 0. If we combine the aux buffer
with the main surface buffer, then the hiz offset may become non-zero.

Midgard has no hardware support for transform feedback, so we simulate
it in software. Lucky us.
What Midgard does do is write out vertex shader outputs to main memory
unconditonally. Fragment shaders read varyings back from main memory;
there's no on-chip storage for varyings. Whether this was a reasonable
design is a question I will not be engaging in this commit message.
What that does mean is that, in some sense, Midgard *always* does
transform feedback uncondtionally, and there's no way to turn off
transform feedback. Normally, we would allocate some scratch memory
every frame to store the varyings in an arbitrary format (interleaved
for simplicity), and then feed that scratch to the fragment shader and
discard when the rendering completes.
The only difference now is that sometimes, for some buffers, we use a BO
provided to us by Gallium and a format provided by Gallium, instead of
allocating the memory and choosing the format ourselves. This has some
limitations -- in particular, it only works at vec4 granularity, so a
corresponding GLSL linkage patch is needed to correctly implement
transform feedback for non-vec4 types. Nevertheless, given the hardware
already works in this admittedly-bizarre fashion, transform feedback is
"free". Or, at least, it's no more expensive than any other rendering.
Specifically not implemented is dynamically-sized transform feedback
(i.e. with geometry/tesselation shaders).
Spoiler alert: Midgard has no support for geometry *or* tessellation
shaders, despite advertising support. They get compiled to *massive*
compute shaders. How's that for checkbox compliance?

Implement ->set_damage_region() region to support partial updates.
This is a dummy implementation in that it does not try to merge
damage rects. It also does not deal with distinct regions and instead
pick the largest quad as the only damage rect and generate up to 4
reload rects out of it (the left/right/top/bottom regions surrounding
the biggest damage rect).
We also do not try to reduce the number of draws by passing all quad
vertices to the blit request (would require extending u_blitter)
