feat(wm): add monitor index preference cmd

This commit adds a new komorebic command, monitor-index-preference,
which allows the user to set the index preference within the VecDeque of
monitors based on the "size" of a display.

This works as the size Rect identifies a unique display on the greater
virtual screen and persists across display connections and
disconnections unless the user deliberately changes the positioning of
the display monitor on the virtual screen.

When a new monitor is added to the state, the monitor preferences will
be checked, and if a preference exists, the new monitor will be inserted
at that index, otherwise, it will be pushed to the back of the VecDeque.
