RFR: 8346439: Allow late binding of module services in custom layers

Tue Dec 17 16:34:49 UTC 2024

Custom module layers allow for lazy loading, late binding, and full customization of module dependencies through the `Controller` API. However, it is not possible for custom layer users to late-bind services, which has prevented some popular application containers from moving to use Java modules.

Add an API to `ModuleLayer.Controller` to allow adding `uses` and `provides` relationships after a module has been defined for custom layers.
