libcamera: camera_sensor: Reorder functions

The CameraSensor class has grown a lot since its creation, with many
functions added for different types of purposes. They are not grouped by
categories in the class definition, generating confusion when reading
the header file. Improve readability by sorting functions by category:

- Getters for static data (model, entity, focus lens, ...)
- Format and sensor configuration accessors
- Properties and controls (including test pattern mode)

Update the .cpp file accordingly.
