libcamera: pipeline: uvcvideo: Initialize CameraData from MediaDevice
The UVCCameraData::init() is the only consumer of the default entry in the media graph, move the lookup of it into the init() function and pass it the MediaDevice. This is done in preparation to extend the CameraData initialization to consume more information from the MediaDevice.
