libcamera: pipeline: vimc: create camera for Sensor B

Browse source 
Create a camera for Sensor B of the vimc pipeline. At this stage only
Sensor B is exposed while the are in total two sensors in the graph.
Going forward Sensor A should also be exposed as another camera. Sensor
B was chosen since the graph is configured correctly for it out of the
box. As we lack control over sub devices formats it's not really
possible to use Sensor A yet with the library.

Once both cameras are registered with the library they should be
extended to provide two streams each, one for the raw output and one for
the output which uses the shared scaler.
