Draft: Added ECM support for SIMCom LPWA modems
- Added ECM bearer support for SIMCom SIM70x0 LPWA modems in simtech plugin
- If ECM is not supported it will fallback to ppp
- ECM autoconnect enabled once and stored in NVM
- APN is set by modem object via AT+CGDCONT.
- PDP ctx authentication in ECM connectivity case is rarely set, most likely while using private networks with Radius server.
- Added modem reset method in simtech plugin
