WebCore classes should be able to iterate over a JS asynchronous iterable
rdar://168664049
https://bugs.webkit.org/show_bug.cgi?id=306024
Reviewed by Chris Dumez.
We implement DOMAsyncIterator which is a wrapper around a JS async iterator.
This allows WebCore code to easily manipulate iterable values, like for
ReadableStream.from.
It is implemented by storing the next method directly in DOMAsyncIterator which
derives from DOMGuarded and the iterator object as a separate DOMGuardedObject.
We export some new methods from JSC, while keeping existing JSC equivalents to
allow LTO.
Covered by added tests using new dedicated internals API.
