Split up streams logic to prepare for PlzNavigate RDH changes.

This was split out from https://codereview.chromium.org/519533002/

StreamHandle is now split into a StreamHandle and StreamInfo. StreamHandle only
manages the stream URL. StreamInfo also contains the headers and other metadata
that the streams_private mechanism uses.

StreamResourceHandler is also split out into a StreamWriter so other resource
handlers may also use it.
