Only show the JIT cores on x86_64(Will have its own issues once we reach that point)
Show AArch64 JIT if running on a AArch64 device(Good luck with that for now. Future proofing though)
As of this commit, it is broken into CPU Settings and Video Settings.
I also simplified the code that is responsible for setting the valid CPU cores and video backends by simply making UI string arrays that get chosen, based on the platform the Android device is running on.
