[roll] Roll fuchsia [fake-display] Switch to library-based Banjo adapter.

This CL deletes the custom Banjo display engine implementation in the
fake display "driver", and switches to the API in the
lib/api-protocols/cpp library.

The library-based adapter uses the types in the lib/api-types/cpp
library, which do input validation on construction. Adopting these types
brings the validations to all tests that use fake-display.

Furthermore, this work gets the driver's code closer to
virtio-gpu-display, in the hope of making future API migrations easier.
