i18n: Account for `load_*_textdomain()` after JIT loading. 

When `load_*_textdomain()` functions are called after WordPress has already attempted just-in-time loading of translations, nothing happens. 

This updates the related logic to retry translation loading when a custom path is set to ensure all translations are available.

Additionally, this also fixes cases where an `en_US.mo` file is provided with non-English strings to override the default language.

Follow up to [59157].
