feat(workflows): add "attribute action" action

This action lets users perform several actions on threads, such as
(un)lock, (un)set as trending, (un)pin, set as non-issue, obsolete, etc.

The action selector shows the action with the codename it has in the
Protobuf enum. We will show a friendly string when we localize the
feature.
