Disable sensitive logs

- PII logs can only appear in VERBOSE level
- logSeverityStrToEnum() no more support VERBOSE level input, only
accept DEBUG, INFO, WARNING, and ERROR.
- developer can set DBG flag from code to have a debug build, the DEBUG
level is automatically promote to VERBOSE.
- uniform log format to [FILE NAME]: [FUNC NAME]: [MSG]
- move from ALOG to LOG on DnsProxyListener
- adjust severity for some logs
- correct print format on uint8_t type
