[kotlin] fix uast annotations

- firKotlinInternalUastUtils: ensure that boxed primitives and String become annotations; otherwise @Nls is missed from the analysis
- AnnotationContext: ensure symbol-based accessor methods are processed; otherwise annotations on properties are ignored
- move tests to k2

^KTIJ-32161 fixed
