Cleanup codebase

for FileSystem.cpp:
Instead of checking if Linux or FreeBSD, check if its not Windows and not OSX. Chances are other operating systems run a DE that adheres to the XDG Desktop standard (.desktop). The check isn't good enough anyways since alternative shells for Windows exist, it will never be an accurate check. In any case this function is unused.

WorldListPage.cpp:
Redo confusing switch statement plagued with fall throughs, now well defined.

LaunchController.cpp:
Remove cringe. Also fix warning and make the unimplemented case(s) more explicit.

VersionProxyModel.cpp:
Add fallthrough for warning suppression.

WorldListPage.cpp:
redo `mceditState`

TranslationsModel.cpp:
Move up definition of `column` variable to when it is needed, clear up switch cases

FlameInstanceCreationTask.cpp:
Fallthrough intentionally

SkinUpload.cpp:
Make `getVariant`

ResourcePack.cpp:
Add new values for 1.19.3+

meta/Index.cpp:
Make clear switch statement behavior

JavaWizardPage.cpp:
Fix case fallthrough

Yggdrasil.cpp:
Fix case fallthrough

AccountList.cpp:
Fix case fallthrough,

WinDarkmode.cpp:
Add an explanation and fix warnings due to FARPROC casts.
