Add getters for rendertarget/device/config

All the classes are implicitly shared, as is the Qt standard, so just
return them as is by value. This is useful when applications split up
their logic and so certain settings are set from different places. (we
see this a lot in practice with QSurfaceFormat for instance) In this case
it is helpful if they can query what they previously stored via the setter.
