RuntimeEffect pipelines must be obtained via this method to avoid re-creating them every frame.

The unique_entrypoint_name comes from RuntimeEffect::GetEntrypoint. Impellerc generates a unique entrypoint name for runtime effect shaders based on the input file name and shader stage.

The create_callback is synchronously invoked exactly once if a cached pipeline is not found.
