We're about to put more than just input assembly data in there so the
name will make a lot more sense. Also, add a comment to make it more
clear that this buffer applys to both VS and TES.

In the C23 standard unreachable() is now a predefined function-like
macro in <stddef.h>
See https://android.googlesource.com/platform/bionic/+/HEAD/docs/c23.md#is-now-a-predefined-function_like-macro-in
And this causes build errors when building for C23:
-----------------------------------------------------------------------
In file included from ../src/util/log.h:30,
from ../src/util/log.c:30:
../src/util/macros.h:123:9: warning: "unreachable" redefined
123 | #define unreachable(str) \
| ^~~~~~~~~~~
In file included from ../src/util/macros.h:31:
/usr/lib/gcc/x86_64-linux-gnu/14/include/stddef.h:456:9: note: this is the location of the previous definition
456 | #define unreachable() (__builtin_unreachable ())
| ^~~~~~~~~~~
-----------------------------------------------------------------------
So don't redefine it with the same name, but use the name UNREACHABLE()
to also signify it's a macro.
Using a different name also makes sense because the behavior of the
macro was extending the one of __builtin_unreachable() anyway, and it
also had a different signature, accepting one argument, compared to the
standard unreachable() with no arguments.
This change improves the chances of building mesa with the C23 standard,
which for instance is the default in recent AOSP versions.
All the instances of the macro, including the definition, were updated
with the following command line:
git grep -l '[^_]unreachable(' -- "src/**" | sort | uniq | \
while read file; \
do \
sed -e 's/\([^_]\)unreachable(/\1UNREACHABLE(/g' -i "$file"; \
done && \
sed -e 's/#undef unreachable/#undef UNREACHABLE/g' -i src/intel/isl/isl_aux_info.c

prologs inflate register pressure, so this can help a lot in the monolithic case
(together with dynamic strides). eliminates spilling from some vertex shaders in
Control that read a ton of attributes per vertex.

this is more explicit than vec2's and hence has fewer footguns. in particular
it's easier to handle with preambles in a sane way.

there's probably room for more clean up but for now this unblocks what I want to

With the exception of some variants for framebuffer fetch (to be addressed in a
follow up MR, this is big enough as it is) -- this switches us to a shader
precompile path for VS & FS. VS prologs let us implement vertex buffer fetch
with dynamic formats, FS prologs let us implement misc emulation like API sample
masking and cull distance, while FS epilogs handle blending and tilebuffer
stores. This should cut down shader recompile jank significantly in the GL
driver. It also prepares us with most of what we need for big ticket Vulkan
extensions like ESO, GPL, and EDS3.
