The SPRX Loader thread spawned in Emulator::Load() invokes
ppu_initialize() and ppu_precompile(), both of which write into the
PPU JIT code cache. On AArch64 Apple Silicon, MAP_JIT pages default
to execute mode for newly created threads, so any write into the
cache from this thread segfaults before the game can boot.
Reproducible on a clean RPCS3 0.0.40-19340 boot of Red Dead
Redemption (BLUS30418) on macOS arm64: the emulator crashes ~12s
into boot with "Segfault writing location 0x300010000" originating
from the {SPRX Loader} thread, never reaching the title screen.
Mirror the W^X handling already used by the PPU thread's
ppu_cmd::initialize handler in PPUThread.cpp: enable write mode at
thread entry and pair it with an RAII guard so execute mode is
restored on every exit path (normal return, early-exit on
Emu.IsStopped(), exception). No effect on x86_64 or non-Apple
ARM64 builds (entire block is inside #ifdef __APPLE__).
