Depsgraph: Remove filtering API

This was an attempt to speed up motion path calculation, which didn't
really work in real world animation files, where animators already
hide and disable all the heavy collections. Filtering approach also
doesn't allow to have multiple frames evaluated in multiple threads
easily.

Filtering also adds extra complexity on keeping the graph in a correct
and consistent state.

Fixes T64057: Blender crash when use motion paths
