Annotations have now retention of "RUNTIME" by default. Java retention is generated as given by kotlin annotation. Annotation rendering changed.

Annotation arguments with default values are rendered as ... if renderDefaultAnnotationArguments is true.
Tests: java retention does not taken into account by Descriptor comparator.
Java retentinon changed to kotlin retention in some tests + one new test with java retention added.
More accurate tests for intentions in byte code (visibility controlled).
