v2.0.0 Add support for ESP32S2 and update ESP-IDF to 4.4 (#4996)
This is very much still work in progress and much more will change before the final 2.0.0

Some APIs have changed. New libraries have been added. LittleFS included.

9ad860758c Fix Memory leak in addApbChangeCallback() (#3560)
* `ledcWriteTone()` added a `apbcallback()` evertime the tone value was non zero.  
* `addApbChangeCallback()` did not detect duplicate callbacks.
* changed the apbcallback list to a double link to support roll forward, roll back execution.  This made the sequences of clock change callback start with the newest registered -> to oldest on the `before` then oldest -> newest after the clock change.  This made the UART debug log output have minimal gibberish during the clock change.
* change how the UART callback handled the MUTEX because if any `apbchangeCallback()` executed a `log_x()` a deadlock would occur.

This fixes #3555

f71a4bd406 Bugfix/detect baudrate (#3188)
* Expose uartStartDetectBaudrate(uart_t *) in esp32-hal-uart.h and call it from HardwareSerial::begin() if baudrate detection is requested (by passing a baudrate of 0) to solve baudrate detection problems

* Avoid a division by zero error in uartGetBaudRate()

41e36a72f3 uartEnd: Unlock mutex before detaching rx and tx (#554)
* uartEnd: Unlock mutex before detaching rx and tx

This should solve the device freezing issue when Serial.end() is called

* Unlock UART MUTEX only for detaching Rx and Tx

* Thanks to @me-no-dev for pointing it out that
   uart->dev->conf0.val can be inside mutex lock
