Bug 1917950 [wpt PR 48085] - Streams: test whether patched then() s…

…ees correct `byobRequest`, a=testonly

Automatic update from web-platform-tests
Streams: test whether patched `then()` sees correct `byobRequest`

See whatwg/streams#1326 for context.

This also updates the `transferArrayBufferView` test utility to be synchronous, which slightly changes the timings of some tests in `streams/readable-byte-streams/general.any.js`.
