esp32/modesp32: Add mcu_temperature() function for C3/S2/S3 devices.

Browse Source 
For ESP32C3/S2/S3 IDFv5 exposes new internal temperature API which is
different to the base ESP32, IDFv4.

Thanks to @robert-hh for cleaner code and testing sensor capability in
these devices.

See discussion #10443.
