Companion global variables refactor (#5328)

* Companion Global Variables refactor to support changes to radio in 2.2

* Update model print for global variables refactor

* Check and if necessary update all flight modes gvar after updating min or max

* Fix loop limit

* Add clear single gvar context menu
Add gvar popup values to model print
Minor fixes
