[desktop] Add mod importer from folder and zip (#3472)

Closes #3125

Adds buttons to the addons page that imports a mod (or mods) from zip or folder.

Currently known to work with mods that provide proper romfs/exefs things, unsure about cheats and such. Also works on mods that just stuff things into the root of the zip.

TODO:
- [ ] test folder more thoroughly
- [ ] cheats
- [ ] test all sorts of mod pack types
