Add a Locale class to package:intl.

* Locale Identifiers are described by
https://docs.google.com/document/d/1kV5lL7kDkHnzvGVBZbWDurwCI_waLaamSw6QwavXjvc/edit
which is not yet available externally. Once an external version is
available, might we want to link to it from dartdoc?

* This CL does not add the LikelySubtags data, so its addLikelySubtags
and minimizeSubtags implementations only align with
CLDR/ICU/ECMAScript for cases where the Target script and region
columns of
http://www.unicode.org/cldr/charts/latest/supplemental/likely_subtags.html
are "Latn" and "US".

* Dartdoc output:
