Qt 3D QML API documentation is missing some properties and functions

Some QML types are missing some properties or functions in the documentation. Although they can be found in c++ side of the documentation, but because some of those types are partially documented in the QML API, people tend to think it is the complete listing and don't see that the QML types are actually inheriting the same c++ types.

For example:

https://doc.qt.io/qt-5/qml-qt3d-render-buffer.html
is missing accessType and updateData()

https://doc.qt.io/qt-5/qml-qt3d-render-light.html
missing everything, although this is an abstract class. Maybe these common properties should be added into DirectionalLight, PointLight etc that are currently missing them.

missing externalRenderTargetSize
