Java runtime should codegen all known modules

[wesbillman]

In the go-runtime, we will generate module stubs for all built/deployed modules. This ensures that we have stubs to be used by modules even if they haven't been imported by that module yet. This makes the devx much better since you can just use types from any module in FTL.

You can see the issue in the demo video recording
