I am working on an upgrade of JLine inside the `jdk.internal.le` module, and I would like to replace the current native bindings with FFM-based bindings (which are now somewhat provided by JLine). But, for that, native access is needed for the `jdk.internal.le` module. We could possibly move the module to the platform ClassLoader, but it seems it might be better to have more control over which modules have the native access.

Suggestion:

     * Returns the module with the given name in this layer only.
