Depsgraph: Remove particle edit code from evaluation

Everything seems to be working without this, which makes since there is no
evaluation-time edit code in master. The only tricky part here would be that
this means we might want to ensure edit structure exists from inside particle
mode in draw manager.

Other point for not having this code in evaluation is that it's possible to
have same object evaluated in different contexts at the same time, and since
edit structures are supposed to be in original object we might run into
threading conflict.
