Apply this change to 2.0.9 (#8131)

* Fix the F_CPU frequency for the ESP32-S3

Hello, I was using the FastLED library and it was complaining about F_CPU not being defined. So, I just noticed that it is not defined for the ESP32-S3 module. So I made this change in the header file and it compiled. Therefore I wanted to propose this change to the HAL library to improve compatibility. Thank you for your time.

* Makes F_CPU generic based on the SoC frequency

Works for ESP32, ESP32C3, ESP32S2, ESP32S3

* Includes ESP32C3 in the F_CPU definition

Necessary for ESP32 Arduino Core 2.0.x based on IDF 4.4
