IDL parser: align with current Web IDL specification

Mostly renumbered and restructured grammar productions.  Notable changes:

- add support for static attributes via StaticMember
- add support for built-in types ByteString and RegExp
- allow trailing comma in enum declarations

Depends on:
IDL parser: drop AttributeOrOperation and StaticAttribute overrides
https://codereview.chromium.org/336733002/
...or else breaks Blink compile.
