libcamera: camera: extend camera object to support configuration of streams

Extend the camera to support reading and configuring formats for
groups of streams. The implementation in the Camera are minimalistic as
the heavy lifting are done by the pipeline handler implementations.

The most important functionality the camera provides in this context is
validation of data structures passed to it from the application and
access control to the pipeline handler.
