The script that generates the format tables does not set every pipe_format.
In practice, the length of the format tables is equal to PIPE_FORMAT_COUNT.
I just added the explicit size to future-proof it.
(If the largest valid format is not part of the format tables,
there will be a mismatch between the array length and PIPE_FORMAT_COUNT)

These headers use the "restrict" keyword, so they need to include
c99_compat.h in case they get included from C++.
Right now, we include c99_compat.h in many needless places, which saves
us. But we're about to stop doing that.

turnip was playing fast and loose with the name, using the R8_G8B8 format
name but actually setting the descriptors up to read G8_B8R8 like Vulkan

But, suspiciously, if you inline fxt1_variance the warning goes away.
What's happening is that the 2nd arg is uint8_t[N_TEXELS][MAX_COMP], so
it looks like we're passing too small of an array in since gcc knows
that `input` is also [N_TEXELS][MAX_COMP]. Fair enough. Fix the
signature to reflect what's actually going on, and remove some unused
arguments while we're at it.

channel datatypes in Mesa are the host's endianness. For example,
PIPE_FORMAT_R32_UINT doesn't do a bswap in and out in u_format_table.c's
pack/unpack functions. So, z32_unorm shouldn't be byte swapping either,
and neither should z24s8 which is also a packed format, and once you've
got those it becomes clear that all of the swaps in this file were
mistaken.
Things would mostly work out because it's unusual to read/write Z/S data
through the GL API, and even for drivers like softpipe as long as the pack
and unpack both swap it could work anyway. However, the bug would be
visible in glReadPixels() with the matching datatype which would hit the
memcpy fastpath without doing another swap.
Caught by a mesa/main unit test on transitioning to using these
pack/unpack functions.

In looking at the profile of dEQP, GLES3 was spending 5-10% of its time in
ReadPixels, and almost all of that is b8g8r8a8_unorm8. It's really slow
because we're getting about 47MB/s by doing uncached reads 32 bits at a
time in the code-generated unpack. If we use NEON to generate larger bus
transactions, we can speed things up to 136MB/s. In comparison, raw
ldr/str read/writes with no byte swapping can hit a max of 216MB/sec.
