It's time to refactor response from an un-cached request object

Although it is partly correct to base the decision on the resHeaderRecord, it is more expected to base the decision on the type of the body.

Currently, if the body is not "Transfer-Encoding: chunked", it is returned from arrayBuffer even if the original body is a readbleStream, but we should use writeFromReadableStream() for this.
