Adam Rice b22ef3a053 Bug 1566341 [wpt PR 17804] - Implement QueuingStrategies in C++, a=testonly 
Automatic update from web-platform-tests
Implement QueuingStrategies in C++

Implement CountQueuingStrategy and ByteLengthQueuingStrategy in C++.

Implementing in WebIDL leads to some changes in semantics:

1. highWaterMark is now a getter on the prototype rather than an
property on each object. This is because adding properties directly on
objects is not usual practice in WebIDL, and is problematic to implement
in Blink.

2. size() is now a function returned by a getter. This is because a
methods in WebIDL must be called with |this| set to a valid object of
the appropriate type, but size() is called with |this| set to undefined.
See https://github.com/whatwg/streams/issues/1005 for more discussion.

These aren't expected to change behaviour of code in the wild, but the
count-queuing-strategy.any.js and byte-length-queuing-strategy.js
tests detect it.

Also add tests that subclassing of CountQueuingStrategy and
ByteLengthQueuingStrategyworks works properly. A previous iteration
of this change broke it.

Streams Tests

The work on the streams tests is closely tracked by the specification authors, who maintain a reference implementation intended to match the spec line-by-line while passing all of these tests. See the whatwg/streams repository for details. Some tests may be in that repository while the spec sections they test are still undergoing heavy churn.
