Depsgraph: Don't tag original IDs for recalc

Tagging original ID introduces a conflict of interest when a separate
graph is created and is tagging objects to be re-evaluated with its
context.

This is part of the problem in T63111: tags within a temporary dependency
graph affects viewport and vice versa, which makes logic to wrongly
consider that something did change in the scene and that baking is to
be redone.

This effectively reverts db3bfd0, but this time everything seems to
be updating fine in the viewport.
