Fix a number of spelling errors and word duplications throughout the comments
within libcamera.
These were picked up with spellintian.
Also one capitalisation of the first word of a \return statement picked
up by checkstyle.py while creating this patch.

Add an initial set of controls to demonstrate how controls are defined.
Proper documentation for each control is missing.

The ControlList class implements a map from control specifier to control
ID. To avoid constant lookups of ControlInfo when using the class in the
libcamera core or in pipeline handlers, the map uses ControlInfo
pointers instead of ControlId values. This is however not very
convenient for applications or pipeline handlers, as they would be
forced to first look up the ControlInfo pointers for the controls they
want to access. Facilitate ease of use of ControlLists by implementing
an internal lookup of the ControlInfo from the controls provided by the
Camera.

Extend the Camera class to expose the controls it supports. Each
pipeline should generate a list of controls supported by each camera it
creates. These are represented by a ControlInfoMap, and an associated
ControlList of default values.

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.
