[K2] Generic inherited members have own dedicated pages

[vmishenev]

Generic inherited members should lead to pages of members from a superclass.

It happens due to KT-62405.

Also, it leads to non-suppressed functions in enum: compareTo, describeConstantable, getDeclaringClass.

Details
KT-62405 results in an incorrect DRI that leads to creating a redundant page for generic inherited members.

After the fix, the following test should be added:

    @Test
    fun `generic inherited members should have correct dri`() {
        inlineModelTest(
            """
                |interface A<T> { fun x(): T }
                |interface B : A<Int> { }
                """
        ) {
            with((this / "function" / "B" / "x").cast<DFunction>()) {
                dri.classNames equals "A" 
                dri.packageName equals "function" 
                // callable ...
            }
        }
    }

__

User-facing: if B extends A and inherits a function, clicking on that function (inside B) leads to a separate page instead of to A (where it's declared).

One more side effect: There are visible "obvious functions" compareTo, describeConstable and getDeclaringClass on enum pages. It should be gone in the default configuration (suppressObviousFunctions =true) after the fix.

In scope of #3349 there was added test which fails because of appearing of getDeclaringClass. Test is located in ObviousAndInheritedFunctionsDocumentableFilterTest in the end of file called should not suppress toString, equals and hashcode of kotlin Enum
