Add support for playing Dusklight using Wii disc images (#2296)

* Add offsets for Wii USA R0/R2, JPN, and PAL
Also fix an oopsie where l_pos and l_normal's offsets were swapped

* Allow loading Wii discs

* Change GameVersion::GcnJpn checks to isRegionJpn()

* Change GameVersion::GcnPal checks to isRegionPal()

* Add platformSelect and regionSelect templates, simplify a ton of code

* Add *_get() macros to simplify REL loads

* Actually accept Wii USA Rev. 2 discs

* Show the Wii USA revision in prelaunch's disc status

* l_normal isn't in Wii RELs, so I'll just hardcode it

* Account for various BLO differences

Fix crash when opening the map on Wii USA Rev 0 and Wii PAL

* Use the streamed version of the file select music

* Update language selection

* Fix the d-pad/cross button text for Wii PAL
Resizing panes that are already 120.0f wide is harmless, so I didn't bother with a GameVersion check

* Fix brightness check discrepancy, use IF_DUSK_BLOCK macros when ideal

* Update docs and the issue template
