feat(color): Add OneBit option to color radios (and Companion!!) (#1994)

* Added OneBit option also to color radios

* Try to work around GH repo owner issue

Original by @raphaelcoeffic in https://github.com/EdgeTX/edgetx/commit/bf4b5d8c0c1e386d5a4852a80d459540bab98ed3

* Add Companion support for radios with external module

* Companion housekeeping - do not display unnecessary hardware section headings

* fix: Rebase cleanup

* fix: LVGL changes

* feat: Move sample mode to a new Ext RF block
