make extension declaration name optional

This CL updates the parser to parse extension declarations where
the extension name is omitted. For more details, see
https://github.com/dart-lang/language/pull/303/files#diff-9b84d2e3c88265bde2eb43544ddb757dR66

This change explicitly does not handle the case `extension on on on { … }`.
A subsequent CL should either make `on` a builtin
or add more lookahead in the parser to allow this edge case.
