Subject: Accessibility Linux: Implement set focus action

This is used by Orca for geometric navigation (aka flat review) to move
the focus around. It is also generally sensible to be able to
programatically move the focus around. This way of moving the focus
is redundant with the action interface's focus action.

Task-number: QTBUG-40048
