feat(modem): Added support for at_raw() command

Browse Source 
at_raw() sends raw string and supports custom pass/fail phrases for the
API to return OK/FAIL. It also returns raw, unprocessed string as
output.
This allows sending custom requests, such as:
* dce->at_raw("", resp, "RDY", "...", 20000) -- waiting for reset
* esp_modem_at_raw(dce, "+++", resp, "DISCONNECTED", "ERROR", 5000) --
exits PPP mode

Closes https://github.com/espressif/esp-protocols/issues/471
Partially addresses https://github.com/espressif/esp-protocols/issues/468
