fix: Refactor camera control interfaces and event arguments

Significantly restructure camera control interfaces and event arguments.
Removed obsolete interfaces like `IHasCameras` and `CameraSelectedEventArgs`,
and introduced generic event argument classes for improved type safety.
Added `IHasCamerasWithControls` for better management of camera controls.
Corrected the `IHasCameraMuteWithUnmuteReqeust` interface name.
Reintroduced the `eCameraControlMode` enum to define camera control modes.
These changes enhance the organization, clarity, and functionality of the camera control system.
