[TOPIC-GPIO] drivers: gpio_esp32: update to use new GPIO API

- Updates gpio driver and device tree files to the new GPIO Config flags
- Implements the new port_* APIs
- Update I2C and PWM Drivers to use new GPIO config
- Add esp32.overlay to gpio_basic_api test
- refactor convert_int_type, regs struct
- remove config_polarity
- add kConfig notes

Tests:
- samples/basic/blinky
- samples/basic/button
- tests/drivers/gpio/gpio_basic_api
- tests/drivers/gpio/gpio_api_1pin

Board:
- esp32 DevKitC V4

Note about interrupts:
The ESP32 requires specifying a CPU interrupt to be used for GPIO
interrupt signals.  CPU interrupts can be either level or edge (or
special) triggered, but not both.
Please check gpio/Kconfig.esp32 for more info.
