[SM64] Settings Rework

[Lilaa3]

Some reorganizing, putting stuff into sm64 specific property groups, new repo settings system, some cleaner ui with more warnings, create simple level button, new warnings for import and export ROMs just because i was adding them to the ui anyways.
Tried to keep this within scope as much as possible.
Please feel free to comment on anything and everything.

merge conflicts are most likely from black formatting commit 7031047

to merge main I suggest

git fetch upstream main
git merge 70310474e4627ae3f0a3a43a81aced4aa1200cf3^ # note ^ at the end for parent commit
# resolve conflicts manually if any
git merge 70310474e4627ae3f0a3a43a81aced4aa1200cf3
# resolve conflicts by accepting all current (rejecting all incoming changes which are only formatting), then run black
git merge upstream/main
# resolve conflicts manually if any

I tested this and it worked pretty well, but I didn't do an extensive test and combover of all the code because there was a lot of changes. I imagine the rest of the code will be good but I need to look at it closer.
