I18N: Add a $locale parameter for remove_accents().

Browse Source 
This highlights the fact that `remove_accents()` is locale-aware and makes it easier to utilize the function with different locales without having to use `switch_to_locale()` or the `locale` filter.

Additionally, this commit relaxes the check for character replacements in German locales to include formal and informal variants of any `de_*` locale, even if WordPress does not have a native translation for some of them yet.

Props malthert, johnbillion, knutsp, ocean90, SergeyBiryukov.
Fixes #54415.
