[TPHD] Add multiple new cheats and a new Screen Mirroring pack (#721)

Thanks to @Ori-Jakob for adding some new exciting graphic packs:
- New Screen Mirroring mode to force the mirror or normal mode.
  This works irrespective of the type of save you have (Normal or Hero mode). It even works on the fly while playing the game.
- The new mega cheats graphic pack which includes the following options:
  - Moon Jump
  - Always Great Spin Attack
  - Rupee Multiplier
  - Damage Multiplier
  - Never Decrease (Ammo)
  - Climb/Crawl Fast
  - Faster Rolling
  - Drop Duration Modifiers
