Fixes #8645

This will search through a components imports, find any imports
that have not yet been defined in the linker and add a definition
which will trap upon being called.

Thanks! Could this be written with a recursive helper that operates on a &ComponentType (or similar) and a LinkerInstance? That'll help remove some minor duplication here and additionally handle the fully general case of all component imports.

Additionally could this return an error for unsupported imports? For example this can't fill in the import of a component or import of a module at this time so I think those should return an error rather than being silently ignored.

And finally, mind adding a test or two for this?
