Change synchronization handshake mode to host controlled mode

For sake of consistency with the new netX90/netX400 GCI-based implementations, the synchronization hadshake mode should be changed from device controlled mode to host controlled mode. This requires adaption of the ExtendedConfigExample as follows:

  /* Wait for synchronization event or trigger/acknowledge sync */
  lRet = xChannelSyncState(ptSyncResParams->hChannel,
    CIFX_SYNC_SIGNAL_CMD,
    0,
    &ptSyncResParams->ulErrorCount);

The legacy packet for setting the handshake configuration HIL_SET_HANDSHAKE_CONFIG_REQ will be replaced with the substitute HIL_SET_TRIGGER_TYPE_REQ which is better comprehensible and less error prone.
The legacy packet will still be supported with the upcoming version for all rcX-based Firmwares, i.e. the netX52 variant, and will be removed entirely in the future.

This requires adaption of:

• Firmware
• API Reference Manual
• Example Code
