Update AbstractWorker, Worker and SharedWorker to match the specification

[Chris Dumez]

Update AbstractWorker, Worker and SharedWorker to match the spec:
http://www.whatwg.org/specs/web-apps/current-work/multipage/workers.html#abstractworker
http://www.whatwg.org/specs/web-apps/current-work/multipage/workers.html#worker
http://www.whatwg.org/specs/web-apps/current-work/multipage/workers.html#sharedworker

Worker and SharedWorker should no longer inherit from AbstractWorker. Web IDL 'implements'
statements should be used instead. Worker and SharedWorker can now inherit from EventTarget
as per the specification.

Why can you remove this?

This basically declares the following in JSAbstractWorker.h but don't generate its implementation in JSAbstractWorker.cpp:
JSC::JSValue toJS(JSC::ExecState*, JSDOMGlobalObject*, AbstractWorker*);

It can be removed for 2 reasons:
- Its implementation is not provided anywhere and it likely build only because it is not used.
- Now that AbstractWorker acts as a partial interface, JSAbstractWorker.* are now empty anyway so this attribute would have no impact whatsoever.
