The screencast portal supports recording a single window,
and presents a list of open windows when that option is
selected. To allow updating that list when windows are
opened or closed, add a new "WindowsChanged" signal that
the portal can listen to.

While the gsetting is available for all who needs it, the Shell might
override it given various hueristics. Expose the decision made by the
Shell via a new property.
Intended to be used by gsd-xsettings as well as xdg-desktop-portal-gtk.
This also add a version property to the API, so that semi external
services (xdg-desktop-portal-gtk) can detect what API is expected to be
present.

The `GetWindows` method gives access to the list of windows for each
application with some of their properties, so utilities such as dogtail
can pick the window of their choice to interfere with using the provided
window id.

Add a D-Bus API that allows the API user to introspect the application
state of the shell. Currently the only exposed information is list of
running applications and which one is active (i.e. has focus).
