An async hook a renderer awaits while it initialises, after the environment extensions load and
before it creates its systems and pipes. Registered as a WebGLLoader, WebGPULoader or
CanvasLoader extension, it lets a package import() backend-specific systems and pipes and
register them in time for the renderer to pick them up. Loaders for a backend run concurrently;
the systems and pipes they register are ordered by their own priority, not by which loader finished first.
