encoding/textpb: add support for MessageSet

This only handles compliant MessageSet extension fields where the field
name has to be message_set_extension.

Current C++ lib allows for different message field names, which is a
possible bug as it makes marshal output possibly contain duplicate names
when more than one field extends the same MessageSet, and makes
unmarshaling confusing as to which field to populate.
