Description of Change

Enables Power Management support for arduino sketches.

API changes

Extended WiFi.setSleep function to accept listenInterval
Added setAutomaticLightSleep function to enable/disable automatic LightSleep (without changing the CPU frequency)

Tests scenarios

Tested WiFi connectivity, BLE scanning, OneWire, TwoWire, SPI, Serial on ESP32, ESP32-S3, ESP32-C3 boards.

@SuGlider @VojtechBartoska is it possible to migrate from patching SDK-Config in github actions to just copy corresponding sdkconfig.defaults.target? that would be a bit more easy editing defaults, separate them for different targets and reuse for some other purposes (i.e. copy for examples, use in CMake build checks).

Actually we need to add this IDF sdkconfig changes to the Lib Builder scripts.
sdkconfig is used by Lib Builder to compile and build all IDF libraries, therefore, when using Arduino, all settings from sdkconfig are setled in the static IDF libs.

The only way to changed sdkconfig and test it is by using Arduino as IDF Component and then build some examples that will verify how PM and light sleep will work.

Found an issue IDFGH-11870 with IDF's UART implementation , it prevents UART usage with automatic llight sleep in some cases.
It would work if we have WiFi/BLE active or some other tasks, which prevents CPU for sleeping too long, however that not seems reliable.
Also I might have a fix for it, so waiting for the IDF maintainers response.

@igrr @VojtechBartoska @SuGlider for a BLE PowerManagement - i dont have ESP32 board with an external crystal, so for that part I would need your help in testing. On an ESP32S3 I'm planning to use Main XTAL as low power source by default.

@tshcherban -
On top of this PR, I'd like to work on an API that will allow the user to set the source clock too.

This is part of another Task which also wants to add Power Management feature based on automatic Dynamic Frequency Scaling (DFS). The proposal is that the user will be able to set the Clock Source for each peripheral and also set it in a Global way whenever necessary in order to increase DFS applicability.

This should be ready for Arduino 3.0.0 final release.
Is that OK for you?

[tshcherban]

Yes, for sure.
Do i need to grant you an access to my repository? so all the changes come from the one codebase.
P.S. however i didnt noticed too much gain from DFS enabled, while just changing modem sleep pattern to the MAX_MODEM and enabling automatic light sleep improved the things significantly.
Also please beware we still have a bug coming from IDF uart implementation, which can lead sometimes to a dedlock (workaroundable via Serial.Flush call).
