Update Settings Window (#2400)

* Load new localization before firing change event

* Update texts in SettingsWindow when locale changes

* Localize settings search

* Update settings search input

- Disable when Credits are scrolling,
so Search Results aren't shown instead
- Select all on single click, as usual for a search bar

* Remove unused IsVisible property

* Fix General tab being unselected on language change

* Fix search results throwing, oops

* Missed using LocRef in EnumSettingsEntry

* Set CultureInfo before loading locs

* Change it to LazyLoc instead

So CheapLoc can export localizations...
