* Fix gathering inherited properties in PSI

* Refacotr KaJ transformer. Change wrapping TagWrapper for getters and setters.

* Add logic to merge inherited properties in kotlin from java sources.

* Remove getters and setters from JvmField properties for DObject, DEnum, DInterface in KaJ.

* Unify InheritedMember DRI logic.

* Fix gathering docs obtained from inheriting java sources in descriptors

* Apply requested changes.

* Resolve rebase conflicts

* Use 221 for qodana analysis

* Move accessors generation into DefaultDescriptorToDocumentableTranslator

* Fix special "is" case for accessors and refactor logic in general
