backends: Add API to switch to predetermined monitor configurations

Browse Source 
This will allows us to support the XF86Display key present on some
laptops, directly in mutter. This is also known, in evdev, as
KEY_SWITCHVIDEOMODE.

The common usage for this key is to alternate between a few well known
multi-monitor configurations though these aren't officially
standardized. As an example, Lenovo documents it as:

"Switches the display output location between the computer display
and an external monitor."

On this patch, we're just introducing the configurations that have been
implemented in g-s-d until now, which go a bit beyond the above
description.
