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.

This adds a function to be used by gnome-shell to get the logical
monitor given a connector name. For now, use the same index integer
method to reference a logical monitor, but this should be revisited by
providing a better API later.

Wrap the existing laptop_display_is_on() method in a public function
that gnome-shell can use to query whether a builtin output is present
and enabled.

This just exposes the type and the singleton getter necessary to make
it available to introspection. We'll expose more functionality as it
becomes needed.
