Added possibility to use ESP32-IDF log insted of redefined one (#4845)

Browse Source 
With this PR user can select to use the original ESP-IDF log instead of the redefined one.

User can also redefine the log function as per [Logging Library](https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-reference/system/log.html#_CPPv419esp_log_set_vprintf14vprintf_like_t) so he can for example redirect logs to a file.

To enable this change just add -DUSE_ESP32_LOG to build flags.
User can also change the default TAG (that now is ES32) to whatever it wants adding '-DTAG="tag_value"' to build flags
