esp32/machine_pin: Implement Pin.toggle() method.

Browse Source 
The actual output pin value is taken from the OUT register, not from the
pad.

Tested with:
- ESP32   low and high Pin numbers
- ESP32C3 low Pin numbers
- ESP32C6 low Pin numbers
- ESP32S2 low and high Pin numbers
- ESP32S3 low and high Pin numbers
