void CreateFlatlandDisplay (fidl::InterfaceRequest<fuchsia::ui::composition::FlatlandDisplay> flatland)

TODO(https://fxbug.dev/42156949): This creates a FlatlandDisplay attached to the "primary"

hardware display (i.e. the only one supported). In the future there will be APIs that allow

clients to enumerate the displays, and to allow creation of a FlatlandDisplay bound to a

specific one of them. For now, attempts to create a second concurrent FlatlandDisplay (or

gfx::DisplayCompositor) will fail.
