Add ESP32-C2 support (#8881) 
* add c2

* Fix typo

* changes from code review

* rm hack needed to compile for c2

* rm `DARDUINO_USB_MODE=1` not needed for c2

* log_e message no RMT support

* correct log_e

* Update esp32-hal-rgb-led.c

* Add component test build for ESP32-C2

* Disable most components for ESP32-C2

* Add missing ADC SOC defines for ESP32-C2

* Add hidden board definition and fix LED pin in variant

* Add default empty zigbee libs and mode

* Change SPI default pins

* change rx1 tx1 default gpio
