Depsgraph: Remove workaround for Blender Internal in viewport

This commit effectively reverts fix T45702 done in 067fe2719a99.

Reasoning:

- Blender Internal is being replaced with Eevee, and will be removed entirely
  rather soon.

- All render engines are planned to have own depsgraph, so such threading
  conflicts should no longer be an issue.

- We don't want to spend time on porting workarounds for EOL things to a new
  design. Less code -- faster the work :)

- If such notifications will end up needed for some other cases, we would
  need to re-implement this a more proper depsgraph tagging/flushing and make
  it to work with all copy-on-write datablocks and everything.
