Merge OWNERS_FOUNDATION into OWNERS_LANGUAGE.

These two groups were the same (except for Kallen, who was
accidentally not included in OWNERS_FOUNDATION and should have been),
so we decided to merge them. Internally, the group is called the "Dart
Language and Core Libraries" team, so `OWNERS_LANGUAGE` seems like the
one to keep.
