Create libraries for non python target when import dep as jar (#465)

The follow-up change to pantsbuild/pants#8812.

### Problem

Since we will now be relying on libraries as a mechanism to express dependencies between targets, we need to process the libraries field for jvm executables as well.

### Solution

Relax the filter in `PantsLibrariesExtension` to process any scala target (not just JarLibraries).

### Result:

In combination with the pants PR above, the following UX is achieved:
