This reverts {rB1693a5efe91999b60b3dc0bdff727473b3bd00bb}
and implements an alternative solution.
The old patch had the problem that the depsgraph would always
evaluate at the current frame of the original scene (even when
`DEG_evaluate_on_framechange` was used). Now it is possible
to evaluate the depsgraph at a specific frame without having to
change the original scene.
