Depsgraph: Tag scene after changing cursor location

While 3d cursor is mainly an UI thing and isn't needed for scene evaluation,
it is stored in scene DNA. This means, operator is inform depsgraph that data
has changed, so all copies of that scene can copy new values.

Fixes lack of visual feedback when changing cursor location in viewport
with copy-on-write enabled.
