Simulation: improve depsgraph integration

A simulation data block has an embedded node tree, which requires
special handling in a couple of places. Some of those places were
missing beforehand.

This also adds a relation to make sure that the simulation is evaluated
after animations on the embedded node tree are evaluated.
