Add HOOK_ON_PLAY_MODE_UPDATE and HOOK_BEFORE_PLAY_MODE_UPDATE

[EmeraldLoc]

• HOOK_ON_PLAY_MODE_UPDATE (hook 66) is called after a play mode is ran in update_current_play_mode, and allows you to override the change level.
• HOOK_BEFORE_PLAY_MODE_UPDATE (hook 67) is called right before, and allows you to override the current play mode.

What this pr allows for is:

• Fully pausing the game in Lua, including time freeze
• Provide a convenient hook for settings values in Expose gHudDisplay #1158
• Setting Mario's model even if the game is fully paused or frozen with time stop

Also, while messing around with the system, I found some crashes, so I fixed them here. If I need to revert it, lmk.
