Expand description

Update the amount of data available at the underlying source of the given |stream|.

Can only be used for streams with an embedding-provided underlying source. The JS engine will use the given value to satisfy read requests for the stream by invoking the writeIntoReadRequestBuffer method.

Asserts that |stream| is a ReadableStream object or an unwrappable wrapper for one.
