LibUnicode: Define is_unicode_*_subtag helpers inline in their header

Browse Source 
The UnicodeLocale generator will need to parse canonicalized locale
strings, and will require using these methods. However, the generator
cannot depend on LibUnicode because Locale.cpp within LibUnicode already
depends on the generated file. Instead, defining the methods that the
generator needs inline allows the generator to use them without linking
against LibUnicode.
