feat: New advanced joystick mode on radio, improvements to Companion and Simulator joystick support (#3111)

* Allow switches on the connected radio to control switches in the simulator via the joystick interface.

* Merge configurable radio joystick interface from banyaszg.

* Add two more 'axis' channels to companion.

* Fix 6POS from USB joystick to simulator.

* Reduce data size.

* Fix build error on B&W radios.

* Add 'Companion' button mode to work with the button logic in the Companion app.

* Build Companion joystick setup layout at runtime.
Change #define names for simulator joystick.
Allow 15 axes and 32 buttons.
Initial support for trim sliders.

* Remove custom joystick button type for companion - use 3 buttons per switch in companion to control simulator switch state.

* Fix joystick constructor calls parameters. Connect some radio joystick trims to simulator widgets.

* Restore 'companion' button type to reduce number of buttons needed. Make trims work via buttons in USB joystick.

* Connect joystick trim buttons to simulator widgets.

* Use companion source names for trims.

* Add encode / decode of usb joystick custom settings to Companion.

* Convert to lvgl layouts.
Update language files.

* Fix generated YAML storage files.

* Fix initialisation error when editing button channel. Cleanup code.
