libcamera: controls: Introduce control-related data types

Add a set of data types to support controls:

- ControlValue stores a control type and value in a generic way
- ControlId enumerates all the control identifiers
- ControlIdentifier declares the types of a control and map their names
- ControlInfo stores runtime information for controls
- ControlList contains a set of control info and value pairs

The control definitions map is generated from the controls documentation
to ensure that the two will always be synchronised.
