Enable organize imports for dependencies between generated contents

[maybeec]

Currently, we observe the behavior, that "organize imports" does not cover importing dependencies of generated code within generated code.

As an example:
If you generate class1 and class2, where class1 depends on class2 and class1 does not generate any imports by template declaration, "organize imports" will not add an import of class2 within class1.

If you generate class1 and class2, where class1 depends on class2 and class1 generates the import declaration of class2 by template declaration, "organize imports" obviously will not remove the import of class2 within class1 as it is needed.
