enum constants in java sources are reported as properties

[yigit]

For the following two inputs:

            enum class KotlinEnum(val x:Int) {
                VAL1(1),
                VAL2(2);
            }

            public enum JavaEnum {
                VAL1(1),
                VAL2(2);
                private int x;
                JavaEnum(int x) {
                    this.x = x;
                }
            }

When traversing declarations in KotlinEnum and JavaEnum, enum constants of JavaEnum are returned as KSPropertyDeclaration instances while enum constants of KotlinEnum are returned as KSClassDeclarations with the proper kind (ENUM_ENTRY)

Java Annotation Processing also returns them as fields for the java source code but i think for KSP, to be consistent, it is better to report them as KSClassDeclarations.

I've not checked what happens with descriptors, will update the bug.

it works fine for the descriptor implementation (they are reported as KSClassDeclaration instances with type ENUM_ENTRY)

[yigit]

this seems not very trivial because PsiEnumConstant does not have a PsiClass that represents that entry :/.
I can work around it by resolving to the descriptor instead. In the test, it resolves to an instance of: EnumEntrySyntheticClassDescriptor (notice the Synthetic in name)
https://github.com/JetBrains/kotlin/blob/master/core/descriptors/src/org/jetbrains/kotlin/descriptors/impl/EnumEntrySyntheticClassDescriptor.java

We could also possibly implement KSClassDeclaration from a PsiEnumConstant but that adds more variety.
