Reviewed by Kentaro Hara.

Move IDL extended attributes to their correct location according to the
latest Web IDL specification. We used to be inconsistent in the positioning
of the extended attributes. This simplifies a lot the code of the IDL parser
and makes our IDL files more standard.

Based on Blink r148345 by Kentaro Hara <haraken@chromium.org>.

No new tests, no behavior change.
