monitor: Move get_suggested() behind behind vfunc

Browse Source 
Only support suggested monitor positioning if the monitor is non-tiled.
Normally this functionality is used by virtual machines to provide a
hint of how to place the virtual monitors, and they don't tend to use
tiled monitors anyway.
