Is your feature request related to a problem?

Recently a community member has mentioned that the current consumption of ESP32 connected to Wi-Fi is too high. While it is possible to reduce current consumption with ESP-IDF, this option is not accessible to Arduino users.

Describe the solution you'd like

To reduce current consumption in Wi-Fi connected state, several things are required:

• Power management should be enabled (CONFIG_PM_ENABLE).
  • Investigate what are the downsides enabling it if it is not turned on at run time.
• FreeRTOS tickless idle should be enabled (CONFIG_FREERTOS_USE_TICKLESS_IDLE).
  • Investigate what are the downsides enabling it if the DFS and automatic light sleep are not enabled at runtime.
• Enabling DFS and automatic light sleep at run time via some API.
• An easy-to-understand example showing how to achieve lower current consumption when Wi-Fi is connected.
• Documentation explaining the caveats (mostly related to peripherals and timers) of enabling the above mentioned features.

Describe alternatives you've considered

Keep not supporting DFS and tickless idle in Arduino. But then everyone keeps thinking that it's not possible to have Wi-Fi connection with lower average current.
