Fix cycles crash when changing viewport display pass

It was possible that render buffers and scene kernel data will be out
of sync because reset and scene update happens in different locks.

This is similar issue we've fixed in the Cycles X branch, so backported
relevant changes from there.

This change removes what seems to be unused feature kernel.

Tracking: Fix "Lock to Selection" option from header causing jump

This change makes the behavior consistent between shortcut and
option from space clip's header.

The only caveat is that the "Lock to Selection" is removed from the
Display popover. This is because it is rather hard to make operator
to render same as regular checkbox. However, shouldn't be a problem
because the setting in popover was redundant.

BLI_array: add BLI_array_deduplicate_ordered utility & tests

Fix typo in Fly mode tooltip

The bug was always around and was introduced with the original code
e2a7168e9680f (2009).

Nodes: Moved group interface panel code to python.

The node group interface panels were still implemented in C.
Now they ported over to python for easier maintenance.

Make Single User: support object data animation

In addition to _object_ animation, now _object data_ (mesh, curve, ...)
animation can now be made single user as well.

This came up in T89369 and while it is possible to do this via the
Outliner [where all actions have to be selected individually], this
seems to be more convenient to be done from the 3DView.

note: usercount of the action is checked now, if it single-user already,
no copy takes place (same thing could/should be done for
single_object_action_users as well).

note2: obdata is made single user as well (otherwise duplicated actions
will be assigned to the same shared obdata - which does not result in
unique animadata which is what we are after here)
