atomic: Use __atomic_thread_fence() when available

This avoids requiring inline assembly for each architecture.
It also fixes some weakly ordered architectures which lacked
said inline assembly (RISC-V, MIPS, LoongArch, etc) and were
thus disasterously broken.

Backport VIRPIL Controls device IDs to SDL2
...
Build (All) / Create test plan (push) Has been cancelled
Build (All) / level1 (push) Has been cancelled
Build (All) / level2 (push) Has been cancelled
Backport of SDL3 fix (libsdl-org/SDL#15418 ).
VIRPIL Controls (VID 0x3344) flight sticks are
misclassified as gamepads by SDL's axis-count
heuristic because they report exactly 6 axes,
matching SDL_GAMEPAD_AXIS_COUNT. Adding them to
the appropriate device lists ensures correct
classification.
Tested on Linux (Fedora 43, kernel 6.19) with:
- R-VPC Stick MT-50CM3 (PID 0x4391)
- L-VPC Stick MT-50CM3 (PID 0x8390)
- VPC VMAX Prime Throttle (PID 0x0196)

__sync_lock_test_and_set() is designed for creating locks, not as
a general atomic exchange function. As a result, it only provides
an acquire memory barrier and isn't guaranteed to actually store
the provided value (though it does on architectures we care about).
__atomic_exchange_n() is supported on GCC/Clang for the last ~10
years, so let's use that instead if available. We will keep the
__sync_lock_test_and_set() fallback around for ancient platforms,
but add a full memory barrier to match the documented behavior.

Someone mentioned that Claude sees this file's previous text and adds "look at
AGENTS.md" to it's TODO list instead of treating it as the thing it should do
first.
If everything decides to prefer AGENTS.md at some point, we'll delete this
file.
A symlink would apparently also work, but it would be the only symlink in the
SDL git repo, so it seemed less disruptive to just copy the file over for now.

Apparently Claude Code won't read AGENTS.md by default at this moment, but
since that's the direction we're moving, let's just add the file Claude
currently looks for and tell it that the actual instructions are in AGENTS.md.
I thought these things were supposed to be less complicated that interacting
with humans, lol.

This hint is documented to not just turn off fullscreen windows going into a
new Fullscreen Space, but also to make the green button on a resizeable
window's title bar do a maximize/zoom instead of make the window fullscreen.
Previously, this only did the former and not the latter (or perhaps it worked
and the defaults changed in a newer macOS, we aren't sure).
Fixes #7470 .

SDL3 + sdl2-compat doesn't give precisely the same error message as
"classic" SDL2 here. To facilitate the transition from "classic" SDL2
to sdl2-compat, allow either one. This allows the "classic" SDL2 test
suite to be run against sdl2-compat, demonstrating that sdl2-compat is
indeed compatible with the version that it's replacing.
