[Downloads] Retain a BlobDataHandle in DownloadUrlParameters.

This allows a caller to extend the lifetime of a blob until the
downloads / resource loader subsystems take over. Without this, an
unfortunately timed revokeObjectURL() call from the originating page may
invalidate the URL before the download has a chance to start the
associated download request.
