boards: add crsfrc driver to ark flight controllers

[AlexKlimaj]

This PR adds the standalone crfs_rc driver to the ark flight controllers. I also added a parameter to start the CRSF_RC driver with a parameter. If it is enabled, the normal rc_input driver is not started.

Any reason to keep crsf_telemetry.cpp alive? In the long-term this is going to be very confusing for the end-users.

Even myself have to still figure this out and the manual doesn't seem to mention this.

Ultimately we need to merge #20829
Those docs are confusing since there is a rc_input/crsf_telemetry.cpp but the docs refer to this crsf_rc driver.

Just tested an ELRS receiver with telemetry on V6X-RT that's looking good.
