Casio GBD200 device support (#6070)

In this pull request I separated the implementation of the GBD200 from the common implementation of GBX100 since during protocol reverse engineering (done here: github.com/dakk/casio-gshock-bt-proto/) I've found some discrepancies in the BLE protocol, and in my opinion it is better to separate since they are too different in many ways.
The flow works from initial pairing, connection, workout / step sync, configuration sync.

The following feature has been implemented and tested:
- [x] Watch connection and handshake
- [x] Config sync
- [x] Goal settings
- [x] Phone finder
- [x] Sport activity start and stop events
- [x] Sport activity sync with segment data
- [x] Step data sync
- [x] Notifications
- [x] Sport activity and OpenTracks
- [x] Alarm setting

Non Casio related edit:
- OpenTracksController.saveToGpx now handles empty activity (since gbd200 has no gps, and cannot handle gps data, running GBLocationService would be useless)

It should also address some of the following issues:

Todo:
