The mipmapped_z = true case is checked against Metal, the false case is smoke
testing the old behaviour (which is still used for 2D arrays).

See 0afd691f29 ("panfrost: clang-format the tree") for why I'm doing this.
Asahi already mostly follows Mesa style so this doesn't do much. But this means
we can all stop thinking about formatting and trust the robot poets to do that
for us.

There are no outstanding commits to these files in any branch, so they don't
need to be considered for the rebasing script. That said, they are massive and
bottleneck the rebasing script, so we'll want to split them out to keep rebasing
efficient.
(Nominally I should make the rebasing script less stupid but with these files
ignored it works pretty well.)

Layer strides are based on the full miptree, and even for single-layer
images macOS always allocates a full one (possibly relevant for
compression). Make sure we do the same, regardless of how many mip
levels the user asked for.
Fixes Darwinia.

The main buffer is twiddled as before, but there's now also an auxiliary
compression buffer that we need to reserve space for.
With compression, the main buffer is aligned less. The macOS logic seems to be
to align to the page size only if the texture is both 3D and mipmapped, *and*
the layer stride is greater than the page size.
That's gated on compression being enabled. Page alignment seems to be needed for
uncompressed twiddled cube maps.

It appears that multisampled textures on AGX have all samples of the same pixel
contiguous in memory, effectively using the layout of a single-sampled texture
with a larger block size. Handle in ail.

pot_level can be greater than the number of levels actually included --
don't overallocate. Fix the issue and add a representative unit test.

The equations for calculating miptree offsets are complicated,
nonobvious, and full of subtle footguns. Worse, the driver doesn't
control the offsets -- it must simply agree with the offsets
implicitly calculated in the hardware. The CTS doesn't adequately
exercise all the corner cases. Make sure we have unit tests that do.
The tests themselves are generated by instrumenting agxdecode to scan
GPU memory after uploading test patterns in a variety of layout with a
Metal application.
Thank you to Asahi Lina and Dougall Johnson for the reverse-engineering
that led to this. The tests selected here are a subset of those used for
the reverse-engineering. The full set may be found in Lina's tilecalc
