Initial support for the ESP32 C6 board (#274)

* Support for the ESP32 C6 board
This make it possible to set board target and build for the RISC-V board on the ESP32 C6 Board.

* Add CI for ESP32 C6
The CI for ESP C6 follow the CI for ESP C3 as they both use RISC-V

* Add ESP32-C6 to  README

* Exclude the CI run for IDFv4.4 using esp32c6

(cherry picked from commit c5825cc)
