Gui: Allow ActionGroups to not remember choice

This is fix to issue mentioned in the #11717, on discord and forum that
for smart dimension tool the chosen tool should not be remembered. This
will ensure that the "smart" tool is always visible on the toolbar and
other tools are accessible in case that such explicit choice is needed.
