Script Editor: Don't switch to 2D/3D viewports when selecting nodes

Selecting nodes in the Scene dock automatically switches to the relevant 2D
or 3D viewport. This behavior can be annoying while using the Script Editor
and wanting to inspect node properties, so it's now disabled by default when
the Script Editor is active.

This new behavior can be changed back to the previous auto-switching using
the `text_editor/navigation/stay_in_script_editor_on_node_selected` editor
setting.
