package/qt5/qt5doc: add package with qt quick demos

Since qt 5.12, quick demos are moved in the qt5doc package.
In order to use quick demos, qt5doc has to be built.
qt5doc is a bit misleading name for the package, while it's
basic content are the quick demos. qdoc tool itself is a part
of qt5tools.

The examples need to be enabled for this package to do anything (because
we don't build the docs themselves), so select it
