Add more games to Metal Auto list (#592)

ARMS: Tested every character and every Map, played a cup as well. It
works flawless in my testing. (If it freezes, that is caused by the
Hypervisor, not Metal. You need to disable the Hypervisor for this game)

Luigi's Mansion 2 HD: I tested every world a bit and had no issue. Isaac
said he specifically worked on it as well

Following games were flawless in my testing, but I only tested earlier
parts of the game so far, a late game part might have an issue,
therefore I will further test these in the future:

- Astral Chain
- Bayonetta Origins
- New Pokemon Snap
