HKSV: Skip updateRecordingActive delegate call if value didn't change

[bauer-andreas]

:recycle: Current situation

As of now, every write to the Active characteristic of the CameraRecordingManagement service is plainly forwarded to the CameraRecordingDelegate. HomeHub write to this characteristic a lot, even though state isn't changed.

:bulb: Proposed solution

This PR proposes to include a check to determine if the active value changed before calling the delegate. This will remove the burden on developers to do this check themselves.

:gear: Release Notes

• CameraRecordingDelegate.updateRecordingActive() is now only ever called if the value actually changed. This is considered a breaking change. It is continued to be called on every startup if recording is enabled, and it will continue to be called on a factory reset (e.g. when all pairings are removed) independent of the current state.

:heavy_plus_sign: Additional Information

This PR includes a breaking change and is planned for the next major/minor release.
