expose logging subsystem for arduino IDE

* introduce `Logging Subsystem` option in arduino IDE
  * introduces `arduino` and `esp_idf` options
* `esp_idf` option sets the `build.log_subsystem` variable to
  `-DUSE_ESP_IDF_LOG`, which is passed into `build.extra_flags`
* `arduino` option is an empty str and therefore no new flags are added
  to `build.extra_flags`
* cannot use `build.defines` as that conflicts with the PSRAM `-D` flag?
