[Streams API] Create CountQueuingStrategy object as per spec
https://bugs.webkit.org/show_bug.cgi?id=146594

Reviewed by Geoffrey Garen.

Source/WebCore:

CountQueuingStrategy is a class part of the Streams API that can be found at
https://streams.spec.whatwg.org/#cqs-class. We had it as js at the tests but the spec says we have to provide it
natively. The class is implemented in this patch by creating its corresponding IDL with the size method using
the [CustomBinding] attribute, that does not create any bindings against the object allowing us full control to
do what the spec requires (just returning 1 without any cast check). The constructor sets the highWaterMark
property taking it from the argument.
