Niklas Söderlund 77100a7578 libcamera: camera: add state machine to control access from applications

There is a need to better control the order of operations an application
performs on a camera for it to function correctly. Add a basic state
machine to ensure applications perform operations on the camera in good
order.

Internal to the Camera states are added; Available, Acquired,
Configured, Prepared and Running. Each state represents a higher state
of configuration of the camera ultimately leading to the highest state
where the camera is capturing frames. Each state supports a subset of
operations the application may perform.
