Support nearest texture filtering in settings dialog

To address #7962

Also fixes a very minor bug whereby texture filtering was only changing the mip map option. Typically this wouldn't matter, but if a user put nearest in their config and wanted to choose different texture filtering in the options it would not override the nearest min/mag filter setting.

I had a go at translating since its one word, but please validate them before merge.

I would prefer that discussion on if this feature should be merged is confined to #7962 and keep this MR discussion for the code only.
