* Reorganize and clean up RGBController API functions
* Add functions to get protected RGBController member values
* Make NetworkClient, ProfileManager, and ResourceManager friend classes so they can access protected members
* Protected previously-public RGBController members
* Information strings (name, vendor, description, version, serial location)
* Device type
* Active mode
* Flags
* LEDs vector
* LED alternate names vector
* Modes vector
* Colors vector
* Zones vector
* Add CONTROLLER_FLAG_HIDDEN to allow plugins to hide controllers from control GUI
* Add update reason codes to RGBController update callback and signal updates on more RGBController events
* Add loop zone types and segmented zone type
* Add matrix map field to segments
* Rework matrix_map_type from using pointers to vector to prevent memory leaks
* Rework KeyboardLayoutManager to return new matrix_map_type
* Add access mutex to RGBController API
* Add per-zone modes ot RGBController API
* Add JSON description functions to RGBController API
* Mountain60KeyboardController's detector was setting the name member directly, this is an outdated convention that breaks the RGBController rework, moved to a Controller member
* Mountain60KeyboardController had some sort of HID redetect logic, this should not be part of the Controller, this will be handled in the future by HID hotplugging
* Both MountainKeyboardControllers defined static variables to keep track of current mode, moved these to class members so that they won't conflict if two instances exist
* Don't send any device updates as part of SetupZones
