Use IETF application error codes for STOP_SENDING frames.

Add ietf_error_code member to QuicStopSendingFrame, and use
IetfResetStreamErrorCodeToRstStreamErrorCode() and
RstStreamErrorCodeToIetfResetStreamErrorCode() to convert to and from
QuicRstStreamErrorCode.  This closely mirrors behavior of QuicRstStreamFrame.

This is the reland of cl/330521460 with
EndToEndTests/EndToEndTest.ClientRstStats fixed.  See b/168041589 for flakiness
caused by original CL.  Locally verified that 100 runs pass both with and
without FLAGS_gfe2_reloadable_flag_quic_stop_sending_uses_ietf_error_code.

Protected by FLAGS_quic_reloadable_flag_quic_stop_sending_uses_application_error_code.
