<pre>Get rid of IsWorkerGlobalScope and ExtendsDOMGlobalObject extended attributes
https://bugs.webkit.org/show_bug.cgi?id=118191

Reviewed by Kentaro Hara.

Remove WebKit-specific [IsWorkerGlobalScope] and [ExtendsDOMGlobalObject] IDL
extended attributes and update the JSC bindings generator to figure this out
on its own.

No new tests, no behavior change.
