allow asset loader pre-registration (#9429)
# Objective
- When loading gltf files during app creation (for example using a
FromWorld impl and adding that as a resource), no loader was found.
- As the gltf loader can load compressed formats, it needs to know what
the GPU supports so it's not available at app creation time.
## Solution
alternative to #9426
- add functionality to preregister the loader. loading assets with
matching extensions will block until a real loader is registered.
- preregister "gltf" and "glb".
- prereigster image formats.
the way this is set up, if a set of extensions are all registered with a
single preregistration call, then later a loader is added that matches
some of the extensions, assets using the remaining extensions will then
fail. i think that should work well for image formats that we don't know
are supported until later.
