feat: Unified logging across z2m/zh/zhc

[Nerivec]

One logger and one level to control all logging for zigbee2mqtt, zigbee-herdsman and zigbee-herdsman-converters.

• Z2M sets loggers for zh/zhc on init.
• Change function names to match syslog levels.
  • Deprecate warn in favor of warning.
• Improve logging consistency across transports (console, file...).
• Print stack when logging Error objects.
• Change default log file to have .log extension for automatic language mode selection in vscode (& others).
• Support namespacing. Defaults to zigbee2mqtt.
  • logger.xyz('message', 'namespace:goes:here');

Goes with: Koenkk/zigbee-herdsman#989
