Change STOP_SENDING frame related APIs to use QuicRstStreamError type.

Change QuicControlFrameManager::WriteOrBufferStopSending(),
QuicSession::SendStopSending(), QuicStream::OnStopSending(), and
QuicStopSendingFrame constructor to take QuicRstStreamError arguments.
Add QuicStopSendingFrame::error_code member.  Remove
QuicStopSendingFrame::application_error_code and QuicApplicationErrorCode.

Previously the error code was stored in an uint16_t, now in a
QuicRstStreamError, which has a wider underlying type of int.  However, the
truncation logic for incoming STOP_SENDING frames in
QuicFramer::ProcessStopSendingFrame() is unchanged.
