The libcamera public API exposes classes that have parts considered
internal. They inherit the Extensible class, and their internal parts
are split into a Private class. Those classes are defined in public API
headers, and their Private counterparts are defined in internal headers
sharing a common file name (in a different directory). Both headers are
documented in the same source file.

For instance, include/libcamera/camera.h contains the public API of the
Camera class, and include/libcamera/internal/camera.h its internal
counterpart. Both are documented in src/libcamera/camera.cpp.

As the internal headers are not part of the public API, they need to be
hidden from the future public API builds. To prepare for doing so, mark
them with the \internal Doxygen directive. Hardcode the Doxygen
INTERNAL_DOCS option to YES to include the internal API. This will be
changed later for the public API documentation build.

Should all internal headers state this \internal directive? Or only
classes which share documentation with both public and internal API?

I don't object, but it might be easier to be consistent or not miss
components if all internal headers are marked to doxygen with the
directive.

That said, we'd probably be able to pick it up as we develop if
something was in the public docs that we wanted to move out so it's not
critical:

The .cpp files that are internal are not included in the public
documentation build, so \internal will not make any difference in them.

I'm OK if we prefer going that way, it can be done on top.
