Fix T82553: Outliner F2 renaming issue when item is out of view

- scrolling would be restricted (usually, if the object to be renamed is
in view, this prevents scrolling away without finishing the rename
operation)
- renaming by typing and confirming with Enter was not possible (you
would have to escape, scroll to the object and use F2 again)
- other shortcuts like A and H are still active instead of being handled
as text input

Avoid all these issue by forcing the item into view using
outliner_show_active / outliner_scroll_view.
