Cannot polyglot java import innerclasses and use them in type signatures

[JaroslavTulach]

We had to mitigate 74c6f99 as one cannot:

• import inner class d434ec5
• import outer class and reference inner class
• importing Outer$Inner yields an Enso compiler problem.

The d434ec5 commit was:

enso$ git show d434ec5963b637c5f0f1131c33cfd85f19681921
commit d434ec5963b637c5f0f1131c33cfd85f19681921

Progress: - Resolving problems with native-image build

• Removing deprecated --initialize-at-buildtime= option.
• On this PR, sun.awt.X11.XSelection.<clinit> method is called from native image build time, and I have no idea why.
  • This method is not included in native image build time on develop.
• native-image does not permit scala.collection classes to be initialized at build time?
• Building substratevm from sources so that I can debug the native-image build process.
• Trying to add as much classes to --initialize-at-buildtime as possible.
• Created Remove deprecated options from native-image #6879 It should be finished by 2023-05-30.
