Add WPT that checks autoAllocateChunkSize cannot be 0

This CL adds a new WPT for the case that a ReadableStream with a byte
source, and hence a ReadableByteStreamController is constructed, with
autoAllocateChunkSize: 0. This should throw a Type Error because
autoAllocateChunkSize cannot be 0, and should rather be positive.
