Camera: Add support for stream combination query
Camera devices 3.5 and later can optionally support
stream combination queries. These use the regular
'StreamConfiguration' structure however in contrast
to normal stream configuration, the query will be
much faster and will not cause any HW/SW side effects.
Additionally it will be possible to run stream
combination queries at any time after the camera
device is open.
Implement stream combination query for the external
camera provider.
