libcamera: camera_sensor: Sort factories by priority
In order to support a default implementation for camera sensors when no better implementation matches, libcamera needs to try "specialized" implementations first and pick the default last. Make this possible by adding a priority value for factories. Newly registered factories are inserted in the factories list sorted by descending priority, and the default factory uses a negative priority to be inserted as the last element. This mechanism may be a bit overkill in the sense that there is no expected use cases for priorities other than trying the default last, but the implementation is simple and easy to understand.
