- Do compiler/architecture checks EARLY, don't waste time doing random
configuration stuff if the user can't even compile in the first place
- MSVC is unsupported, I assume? So add a check to disallow. There's
literally no MSVC or MSC_VER checks anywhere, so...
- Rather than using the MSVC architecture definitions, use our own
`ARCHITECTURE_arm64` et al. Hijacking existing "standard" definitions
is a very bad idea. Also makes it more readable in CMake
- Change the x86 host check to `x86|amd64`. Some systems still refer to
themselves as x86 despite being 64-bit for... reasons, and I saw one a
very long time ago that referred to it as amd64. This should
basically never come up, nor is it really relevant given that FEX is
for arm64... but it kinda annoyed me so whatever.
TODOs:
- Should we check `CMAKE_SIZEOF_VOID_P (equal) 64`? I don't think anyone
is even trying to compile this thing on armv7 or older, but might as
well? maybe?
- What's the status of *BSD, Solaris, macOS? Technically macOS does
support Wine, not sure about the others.

X11 has an attribute that was causing function declarations to be
missed.
These definitions exist in XLibint.h
eg:
```cpp
extern void _XEatData(
Display* /* dpy */,
unsigned long /* n */
) _X_COLD;
```
This `_X_COLD` attribute was causing these function definitions to get
missed.
This is very useful for extracting function definitions for thunks.
Keep it in upstream to not get lost.
Sometimes it can munge a definition but it is usually fine.
