libcamera: CameraManager: Remove ::get(dev_t)
The CameraManager::get(dev_t) implementation was provided only for the
V4L2 Adaptation layer. This has now been replaced with the use of the
public SystemDevices property.
Remove the deprecated function entirely, along with the camerasByDevnum_
map which was only used to support this functionality.
This is a clear (and intentional) breakage in both the API and ABI.
