Fix/workaround geometry nodes not working with deformation motion blur

Always assume geometry nodes produce potentially animated meshes or point
clouds. In general it is hard to check if geometry nodes are animated, and
for modifiers this was already weak.

The better solution will likely involving checking which geometry was
modified by the depsgraph on frame change, to replace the current mechanism
of manually checking for certain types of modifiers and animation.
