Ryan Houdek f2c8adf7a3 OpcodeDispatcher: Validate instruction encodings with crc

PR #5902 technically introduced a bug where we would read past the end
of bounds for thunk instructions when full smc was enabled. Luckily this
never occurs in practice as the Mono hacks never are on VDSO boundaries,
and no one is expected to enable full smc detection really.

Switch this path over to using crc32 unconditionally. This raises our
minspec technically to armv8-a+crc, but nothing that matters shipped
without crc so it's fine.

This also is a minor speed and JIT size reduction due less branches
polluting the BTB. But really only for mono/unity games.
Requires revving the DiskCache version again.
