Each of the three spin-then-sleep semaphore loops watches a single
atomic word, but ShortSpin() has no way to know that: it spends its
share of SPIN_TIME_NS in batches of eight isb, and every one of those is
a pipeline flush. arm64 can watch the word itself, so ShortSpinOn()
does, and the loops that hold their whole predicate in one word take it.
Hosts that cannot watch an address keep the old spin.
Inspired by Whatcookie's work on arm64 for rpcs3.
Vulkan render fixes (GS device backends), Oboe audio backend, GameDB armsx2_overrides.yaml override loader, EE+VU mac-port recompiler graft, PGO=optimize, and the VU-slam fix: an Android-only force-float in VMManager::SetEmuThreadAffinities (the slam was thread pinning locking the VU1 worker off the prime core, not the VU codegen). Also: CPU-name SoC-property fallback, Mali VK attachment-feedback-loop crash gate, MediaTek fbfetch disable, and on-device thread-placement diagnostic helpers.
The recompiler grafts and GS deltas are unguarded and land in the shared core (they reach the mac/Linux arm64 builds) - see REFACTOR_STATUS.md items 2 and 3 for the reconciliation this still needs; the VU graft is reducible to just the force-float fix.
This caused the WaitGS() issued from the main thread when applying
renderer settings (while the core thread was paused) to return
immediately, and a massive race resuming.
