This updates a3xx/a4xx/a5xx to fix the fetchsize to "PITCHALIGN" (called
"MINLINEOFFSET" by the a3xx docs), and some simplifications to make things
more like a6xx. Also similar simplifications for a2xx layout code.
The pitch can always be determined using a simple calculation from the base
level pitch, so don't pre-calculate a pitch for each mipmap level.

Accidentally broke this when rebasing the offending commit.
My use case with non-zero explicit offset is UV plane of UBWC NV12, and
only the UBWC slice offset is used for the UBWC sampler, so I didn't catch
it immediately.

Reduce linear alignment, and rework the layout code a bit.
This rework has a side effect of also increasing the alignment on linear
levels of tiled (non-ubwc) cpp=1 and cpp=2 layouts. Since we should be
UBWC for those cases anyway, its not a big loss.

"FETCHSIZE" is actually a "minimum pitch" or "pitchalign" value that's
relevant for mipmaps. The 0 value means 64-bytes. Understanding this allows
some simplifications and will make it possible to use less alignment on
linear formats.

This uses a meson builtin to handle -fvisibility=hidden. This is nice
because we don't need to track which languages are used, if C++ is
suddenly added meson just does the right thing.

I'm working on fixing the 3D layouts in CI so we can stabilize it, but I
wanted unit tests using the texturator scripts to make sure I don't break
things. This also makes a5xx and a6xx layout easily comparable again.
This is a straightforward move of the code with prsc references replaced
by arguments in the style of fdl6.

The HW requires a log2 width/height of the level 0 meta_* size in the
descriptors, making it pretty clear that UBWC mipmapping is all
power-of-two sized. Fixes a bunch of failures in the upcoming unit UBWC
layout unit tests.

Using texturator on a P3A at 1024x1024, RG8 has log2w/h of 6x7 instead of
R16I/UI's 6x8. The other blockw/h I verified other than cpp=1
(R8/R8I/R8UI didn't use UBWC) and 32 (would need a bigger type).

For compressed formats, we need to align the number of blocks, not the
logical number of pixels in the texture. Only compressed formats have
block width/height > 1, so we can just unconditionally multiply the
alignment by the block width/height.

Back in a2xx, HW pitches were in pixels, so storing that was reasonable.
Ever since then, the HW wants pitches in bytes, and we have only one
instance of using pitch in pixels in the code (a3xx sysmem path).
Flip things around so that only a2xx has to worry about the cpp for
looking at pitches.

Found from piglit fbo-generatemipmaps failures, then tracked down with the
texturator test. The piece that really revealed things was finding that
1024x1 linear RGBA8 on the older blob drivers would have a pitch of 5120
instead of 4096, and the following levels minified that pitch.
Fixes ~124 piglit tests (~8.5% of piglit failures) on cheza.

Trying to work out texture layout by remembering what things looked like
in texturator is hard. Instead, let's use texture layouts from tracing
the blob as a source of truth to make sure that we pick the same layouts
they do (and don't break known-good ones). More testcases will be added
as I fix layout bugs.

Tell users what the base address of the image needs to be aligned to.
These values are based on experimentation via passing an offset to
vkBindImageMemory with turnip and seeing if tests still pass. Note that
r8g8 is also special in this regard, however it actually has an
increased alignment (in bytes).

This gets us shared non-UBWC layout code between gallium and turnip.
Until I fix up the rest of gallium to handle UBWC mipmapping, we do the
single-level UBWC setup in gallium as a fixup after layout.

We pass in all the parameters for setting up the layout, though freedreno
still sets a few of them up early (since it uses layout helpers in making
some decisions about the layout setup parameters that will be cleaned up
once krh's blitter work lands).
This lets us start using some of the fdl_* helpers and have more obviously
matching code between gallium and turnip. We can't yet use the fdl_* UBWC
helpers, since the gallium driver doesn't do UBWC mipmaps (which I'm
working on in another branch).

We can just bake the UBWC-goes-first delta into the slices at setup time.
I did have to fix up the resource shadowing swap path to swap the slice
fields, as it was missing and regressed the format reinterpets otherwise.
