Depsgraph: Add extra name tag for operation nodes

The idea here is to address issue that name on it's own is not
always unique: for example, when adding driver operations the
name used for nodes is the RNA path (and multiple drivers can
write to different array indices of the path). Basically, now
it's possible to pass extra integer value to distinguish
operations in such cases.

So now we've already switched from sprintf() to construct unique
operation name to pass RNA path and array index.

There should be no functional changes yet, but this work is
required for further work about replacing string with const
char*.

Fix T49826: NEW-DEPSGRAPH - Texture is not updated after changing its space color

The issue was caused by image ID nodes not being in the depsgraph.

Now, tricky part: we only add nodes but do not add relations yet. Reasoning:

- It's currently important to only call editor's ID update callback to solve
  the issue, without need to flush changes somewhere deeper.

- Adding relations might cause some unwanted updates, so will leave that for
