Add WritableStreamNative methods for use by PipeTo

Add WritableStreamDefaultWriter::GetDesiredSizeInternal() method which
returns the same information as GetDesiredSize() but without creating
any JavaScript objects. Instead it returns a base::nullopt to indicate
that the stream is errored.

Also add accessor OwnerWritableStream() to WritableStreamDefaultWriter
and accessors IsErrored() and IsWritable() to WritableStreamNative.

Also fix a minor bug in the WritableStreamNative constructor (it didn't
return after throwing an exception).
