-----------
Implement byte stream support for fetch responses
rdar://162107262
https://bugs.webkit.org/show_bug.cgi?id=300312
Reviewed by Chris Dumez.
We add support for readable byte stream as body of fetch responses and requests.
This is gated by a specific feature flag.
To implement that support, we have to change the way to read from a fetch
stream body.
We remove the ReadableStreamSink interface and infrastructure (including
JS-builtin), and instead use plain C++ via the ReadableStreamToSharedBufferSink
class.
We change FetchBodySource as well as it is now a source for the C++
ReadableStream code path.
We add a way for a byte stream to start synchrnously (previously it would wait
for the next micro task to be started), and we use a highWaterMark of 1 so that
the stream will start pulling synchronously as this is the current model we
have for fetch non byte streams.
Test: http/wpt/fetch/fetch-byte-stream.html and existing fetch tests.
