Refactoring some old code in locale providers. The test case data have also been modified due to: - There's a bug in `LocaleProviderAdapter.toLocaleArray()` where it did not handle the case for `no-NO-NY`. - `Locale.toLanguageTag()` won't handle legacy Java locales, e.g., `ja_JP_JP` and falls back, so comparing locales using language tags does not work for those locales. Changed to compare with `Locale.toString()` instead.
