IDL parser: add StaticAttribute production

IDL parser: add StaticAttribute production

This is a straight upstream from Blink's IDL parser, which will allow
us to drop some overrides there, which in turn will allow us to update
this parser to use the grammar of current Web IDL, where static
attributes are supported differently (via a StaticMember production
that handles both static attributes and static methods.)

Preparation for:
IDL parser: drop AttributeOrOperation and StaticAttribute overrides
https://codereview.chromium.org/336733002/ (in Blink)

...and ultimately for:
IDL parser: align with current Web IDL specification
https://codereview.chromium.org/329853005/

PTAL.

Temporary migration patch to make it possible to land
https://codereview.chromium.org/329853005/. This patch alone does not break, or
otherwise affect, Blink's IDL parser. It overrides both AttributeOrOperation and
StaticAttribute.

Thanks!

Could you put these comments about related CLs in the Description, so the
relation
is clear at a glance and in the commit log?

LGTM, thanks!

AFAICT, this is the *first* CL in this sequence.
