This commit does the following to get tests passing for MSVC/AArch64: * Implements spin_delay() with an ISB instruction (like we do for gcc/clang on AArch64). * Sets USE_ARMV8_CRC32C unconditionally. Vendor-supported versions of Windows for AArch64 require at least ARMv8.1, which is where CRC extension support became mandatory. * Implements S_UNLOCK() with _InterlockedExchange(). The existing implementation for MSVC uses _ReadWriteBarrier() (a compiler barrier), which is insufficient for this purpose on non-TSO architectures. There are likely other changes required to take full advantage of the hardware (e.g., atomics/arch-arm.h, simd.h, pg_popcount_aarch64.c), but those can be dealt with later.
