[whatwg/streams] Fix missing check for autoAllocateChunkSize == 0 (#1098)

The reference implementation of [`SetUpReadableByteStreamControllerFromUnderlyingSource`](https://streams.spec.whatwg.org/commit-snapshots/660d259fa263e3c0646415a41b6e7b9a13ac4d04/#set-up-readable-byte-stream-controller-from-underlying-source) was missing step 9:
> 9. If _autoAllocateChunkSize_ is 0, then throw a `TypeError` exception.

This missing check was surfaced by a recently added WPT test (web-platform-tests/wpt@d7c07ed6cc486f3335c6a18a62ebae7517803237), but we did not yet roll WPT for this repository, so it went by undetected. This PR adds the missing check, and updates WPT to the latest version.
