Laurent Pinchart a1c6b2b641 libcamera: controls: Support accessing controls by numerical ID
The ControlList class has template get() and set() methods to get and
set control values. The methods require a reference to a Control
instance, which is only available when calling them with a hardcoded
control. In order to support usage of ControlList for V4L2 controls, as
well as serialisation and deserialisation of ControlList, we need a way
to get and set control values based on a control numerical ID. Add new
contains(), get() and set() overload methods to do so.

As this change prepares the ControlList to be used for other objects
than camera, update its documentation accordingly.

Laurent Pinchart a1772d44e8 libcamera: controls: Default ControlList validator argument to nullptr
The ControlList constructor takes a validator pointer that can be null.
Set its default value to nullptr to simplify code in users of
ControlList.

Niklas Söderlund bf0915a4e8 libcamera: ipa: rkisp1: Add basic control of auto exposure
Add an IPA which controls the exposure time and analog gain for a sensor
connected to the rkisp1 pipeline. The IPA supports turning AE on and off
and informing the camera of the status of the AE control loop.
