drivers: video: controls: add the BASE and CAMERA controls

Add all the base controls present like they are in Linux into Zephyr,
limited to those that can apply in the current system:
- Buttons are left as integer for now.
- Some description is modified to fit the Zephyr situation.
- For the minimum number of buffer, Zephyr uses a different mechanism.
- No audio support through the video subsystem.
- Homogenize the wording
