Unminimize minimized windows passed to meta_workspace_activate_with_focus()
by calling meta_window_activate() on them instead of meta_window_focus()
and meta_window_raise(). This fix makes sense because for the existing
usage inside Mutter meta_workspace_activate_with_focus() is never called
on a minimized window and for calls from outside Mutter there is no
point in focusing a minimized window without unminimizing it first.
Add a doc comment to meta_workspace_activate_with_focus().
