Handle APB frequency change (#2250)

Browse Source 
* Add APB change callbacks and move cpu code to own file

* Properly set esp_timer and FreeRTOS tick dividers

* Improve updated devisors

* No need to update REF_TICK yet

* Add initial handling for UART baud change

* fix uartWriteBuf and uartDetectBaudrate

* trigger callbacks even when APB did not change

* toggle UART ISR on CPU change

* add XTAL freq getter and add cpu freq validation

* Support CPU frequency changes in I2C (#2287)

**esp32-hal-i2c.c**
* add callback for cpu frequency changes
* adjust fifo thresholds based on cpu frequency and i2c bus frequency
* reduce i2c bus frequency if differential is too small
**Wire.h**
* version to 1.1.0

* Implement clock change for the other peripherals

* remove bad CPU clock values from the menu

* Add note to CPU freqs that support WiFi and BT
