Re: [csswg-drafts] Consider Canonicalization of language tags in :lang() selector maching (#4154)

Discussion in i18n WG meeting:
 
- tags with xlang eg. zh-yue -> yue
- deprecated tags can be mapped, ie. grandfathered tags
- capitalisation

possible additions need discussion

for canonicalisation of things like script tags use CLDR mechanism
