Simplify QuicStreamSendBuffer::SaveStreamData().

This method is called at two places in production:
QuicCryptoStream::WriteCryptoData() and QuicStream::WriteOrBufferDataAtLevel(),
both times with an iovec created locally from an absl::string_view.  In order to
reduce complexity, this CL changes SaveStreamData() to take an absl::string_view
directly instead of an iovec.
