Subject: [PATCH 01/11] introspect: Include `sandboxed-app-id` as well

App IDs in gnome-shell don't match AppStream, Flatpak or Snap IDs. For the
desktop portal, the latter two are more relevant, so include it in the
returned information.

Subject: [PATCH 03/11] introspect: Fix whitelist check

The whitelist is a list of well-known D-Bus names, which we then search
for the unique name we get from the method invocation - unsuccesfully.

Fix this by watching the bus for any name in the whitelist in order
to maintain a map from wel-known to unique name that we can use for
matching.

Subject: [PATCH 11/11] introspect: Add AnimationsEnabled property

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.
