dump important build_flags after compile

Usermods and Features:
  USERMOD_AUDIOREACTIVE  UM_AUDIOREACTIVE_USE_NEW_FFT  USERMOD_AUTO_PLAYLIST
  WLED_DISABLE_LOXONE  WLED_DISABLE_ALEXA  WLED_DISABLE_HUESYNC  WLED_DISABLE_MQTT  WLED_DISABLE_INFRARED  WLED_DISABLE_ADALIGHT  WLED_DISABLE_ESPNOW
   WLED_ENABLE_DMX_INPUT  WLED_USE_PSRAM_JSON
WLEDMM Features:
  WLEDMM_FASTPATH

note1: I have no idea about specialties of python - it could surely be done in a "more elegant" way.

note2: the lists sometimes contain duplicates.
