Get rid of optional compilation flags

[Miepee]

Optional compilation flags are neat in concept, but in reality are very prone to breakage with the way on how we apply multiple patches at once.
Currently we have the following flags:

• Debug
• Optimize
• QoL
• Accessibility
• Nonlinear
• randomizer
• Bombless PBs
• Missiles without Mains
• Unhidden Map
• Unhidden Map Doors
• Nerf Geron Weaknesses

I'm not quite sure how to handle Debug and Optimize.
QoL can probably be assumed default?
Accessibility might be difficult since we're modifying graphics. Might be possible to just create new enemy types and make room edits that change all the affected enemies? Maybe we can change the respective enemy code to load different graphics instead based on a rom flag?
For nonlinear see #345.
Randomizer has a similar state and should just be assumed default.
Bombless PBs should be easily done with a rom flag
Same goes for Missiles without Mains
Unhidden Map and Unhidden Map Doors I'm not quite sure how to handle either.
Nerf Geron Weaknesses sounds similar to accessibility, but instead of changing enemy graphics we're changing their weaknesses.

Debug might best left as a compiler flag, but a rom flag would probably work too

Optimize can be made permanent, it doesn't change any behavior

I thought we were forcing accessibility anyway? Adding new enemy types is ok I guess, as long as we don't need more than 50 new sprite IDs (also you'd be doing spriteset edits, not room edits). The sprites' init functions could overwrite the graphics, at the cost of more lag during transitions (or add some sort of switch/case in the function that loads all the sprite graphics)
