4770d6c01d format/fxt1: Clean up fxt1_variance's argument list
gcc 11 warns:

../src/util/format/u_format_fxt1.c:940:22: warning: ‘fxt1_variance.constprop’ accessing 128 bytes in a region of size 64 [-Wstringop-overflow=]
  940 |    int32_t maxVarR = fxt1_variance(NULL, &input[N_TEXELS / 2], n_comp);

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.

69c2a472c2 u_format: Add restrict to fn pointer and manual format pack/unpack/fetch
MSVC warns (loudly) about a mismatch between the generated functions in
u_format_table.c and the definition of util_format_[un]pack_description,
specifically having 'restrict' in the function but not in the pointer
type in the struct.

So, add 'restrict' everywhere - to the function types, and to the rest
of the implementations that are assigned to those structs.

v2: util_format_unpack_description is used in gallium/auxiliary/translate

Fixes: 5785fdac ("u_format: Mark the generated pack/unpack src/dst args as restrict.")

a46b73ee25 mesa: Move the FXT1 compressor/decompressor to util/
softpipe failed at handling FXT1, despite exposing it, because we didn't
have a fetch function for it in the util/ format table.
