We have only a few callers of unpack that do rects, so add a helper that
iterates over y adding the strides. This saves us 36kb of generated code
and means that adding cpu-specific variants for RGBA format unpack will be
much simpler.

We were declaring the temps, then in the same order declaring
assignments to those temps. The code is more legible (and shorter)
with the assignments moved in place.

The code was doing the bit-shift trick, but not accounting for the
rounding necessary which the Mesa unpack code was previously doing.
Using the helpers prevents a regression in
KHR-GL46.copy_image.smoke_test on iris as we consolidate the
pack/unpack code.

A couple of problems were discovered after this series was merged that
cause breakage in different configurations:
(1) It seems that using -mf16c also enables AVX, leading to SIGILL on
platforms that do not support AVX.
(2) Since clang only warns about unknown flags, and as I understand
it Meson's handling in cc.has_argument() is broken, the F16C code is
wrongly enabled when clang is used, even for example on ARM, leading
to a compilation error.

We were calling the table-based unpack functions from inside the pack and
unpack table's methods, so if anything included these pack functions (such
as a call to a table-based pack function), you'd pull in all of unpack as
well.
By calling them explicitly, we save some overhead in these functions
(switch statement, address math on the zero x,y arguments) anyway.

Like we just did for pack functions for freedreno, it will be useful to be
able to pick out a specific rgba unpack function instead of going through
the table.

A single format either had the float, the sint, or the uint version.
Making the dst be void * lets us store them in the same slot and not have
logic in the callers to call the right one.

Some of the generated functions can be useful without going through the
format table (filling border color struct in turnip). By not calling these
functions through the format table, we should eventually be able to garbage
collect the unused packing functions, and also allows LTOs to happen.

This implementation was removed by 8b8af6d3 ("gallium/util: Switch
util_float_to_half to _mesa_float_to_half()'s impl.")
It was not actually broken, but _mesa_float_to_half() implements
round-to-nearest-even, whereas util_float_to_half() implemented
round-to-zero. So rename it appropriately.
GL actually never cares about rounding (except a broken piglit test),
however d3d10 very much does and requires RTZ for float to half
conversion. Moreover, apparently at least radeon gpus actually always
do RTZ when doing RT writes (and I'd suspect for shader image writes
as well). Hence it seems appropriate to hook up this rtz function to
the format instead. This will cause llvmpipe and softpipe to use rtz
rounding for clears with half float formats, and softpipe would use rtz
behavior for rt writes as well (llvmpipe has that hardcoded), not sure
if "real" hw drivers hit this function for much.
(For shader opcodes would still need to figure out what rounding to use
appropriately, but this is a question for another day.)
Note should probably unify with _mesa_float_to_float16_rtz. Unclear at
this point which one is better, so just restore previous function here.

To make PIPE_FORMATs usable from non-gallium parts of Mesa, I want to
move their helpers out of gallium. Since u_format used
util_copy_rect(), I moved that in there, too.
I've put it in a separate directory in util/ because it's a big chunk
of related code, and it's not clear to me whether we might want it as
a separate library from libmesa_util at some point.
