Uses `git --no-pager diff --exit-code HEAD` instead of the two-step check used before. Also shows the diff if it exists so you can see changes at a quick glance.

Bash is already the default on Linux runners.
Just a bit cleaner and less lines. Also cleaned out some unneeded
comments from the template.

Previously, FEX would use `$HOME/.fex-emu` for its data and config if
`XDG_CONFIG_HOME` and/or `XDG_DATA_HOME` were unset. This doesn't follow
XDG, so instead we do a fallback to `$HOME/.config` and
`$HOME/.local/share` respectively if XDG env vars are unset. Also,
pre-emptively creates those directories since `~/.local/share` and
`~/.config` existing is technically not a guarantee if XDG dirs are unset.

ankerl::unordered_dense is faster on average and has less memory usage
than tsl::robin_map. It is pretty significantly faster than std but
we'll keep that as is for now.
Obviously, this will need a lot of testing.

These three objects are easy enough to move out of the static namespace.
They were causing atexit registrations for deallocating memory.
Removes three `atexit` registrations that contributes to crashing on
exit.
Integrate Zydis as an optional dependency to enable x86/x86-64 guest
instruction disassembly during JIT compilation.
Build with -DENABLE_ZYDIS=TRUE.
Use FEX_X86DISASSEMBLE=1 at runtime to output guest x86 instructions
for each compiled block.
Applications can use this to ensure they've grabbed the whole XSTATE
correctly. UML uses it to determine if the FPState was correctly saved.
Also adds a unittest to ensure the same correct behaviour.
For #5206
Turns out the Linux kernel's definition of `MINSIGSTKSZ` and glibc's
definition of `MINSIGSTKSZ` don't match.
The linux kernel has a massive comment about it in `arch/x86/kernel/signal.c`.
Also adds a unittest for it.
For #5206
Previously, changes to externals were also tracked, resulting in
absolutely hilarious abominations like https://github.com/FEX-Emu/FEX/actions/runs/20498228017/job/58901276463?pr=5162
So rather than dealing with that weird action, just fetch the main
branch and run a `diff --name-only` with the PR's merge base with main.
This is how I've done several dozen diff-based scripts (license headers,
clang-format, etc) and it works perfectly, so let's just use this.
Should run quicker too but don't put any money on it.
I also went ahead and removed a bunch of unnecessary quotations cuz
wynaut.

This is fundamentally a frontend only problem, and also Linux only.
Moves it to the frontend where it belongs.
There's likely more things in Allocator.cpp that can be moved to the
frontend but this is the first thing.

UML disables ASLR using a personality. FEX in the ELFCodeLoader was
accidentally erasing personalities. This caused UML to do a bootloop
trying to repeat disable ASLR.
It now gets ASLR disabled, but fails shortly afterwards.
For #5206
eb95a959bc (#5171) did not keep the interface
file in sync with the output of DefinitionExtract.py. Some definitions were
reordered in the Vulkan headers.
There also is no "conflict" about CUDA extensions; instead, the previous
update didn't reflect that the new headers fully hide beta extensions.
