atomic: Fix infinite recursion in SDL_CompilerBarrier() fallback
...
Build (All) / Create test plan (push) Has been cancelled
Build (All) / level1 (push) Has been cancelled
Build (All) / level2 (push) Has been cancelled
On some platforms, SDL_MemoryBarrierRelease() is defined to
SDL_CompilerBarrier(). If SDL_CompilerBarrier() is also defined to
the fallback spinlock acquire/release, then we will infinitely
recurse in SDL_UnlockSpinlock(). Avoid this by not unlocking the
temporary spinlock we create.

...
Build (All) / Create test plan (push) Has been cancelled
Build (All) / level1 (push) Has been cancelled

This is the (slightly) more standard way to accomplish it.

atomic: Use DMB ISHLD for aarch64 acquire barrier
...
Build (All) / Create test plan (push) Has been cancelled
Build (All) / level1 (push) Has been cancelled
Build (All) / level2 (push) Has been cancelled
This is a little more efficient than a DMB ISH and matches what
GCC, Clang, and MSVC generate for a C++11 acquire fence.

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.

Translate conditional effect direction instead of hardcoding it to 0
...
Provious code wrongly assumed that direction is not an important part
of conditional effect. Moreover, if there's need to hardcode polar
direction, the default should be 0x4000 (north).
For one axis affects, a direction of 0 means complete lack of force, if
a FFB-enabled device takes direction into force calculation. A sine function
graph can be used to represent the resulting forces where X is the input
direction and Y is the force multiplier (360 degrees equals to 1).
This fixes conditional effect playback on Moza Racing devices, which do
not ignore direction field.
