Functional supertype is rendered as a non-existing type name

[fzhinkin]

Describe the bug
If a classifier extends a functional type, rendered documentation uses FunctionX as a super type name. However, such types do not exists (the closes thing we have is kotlin.jvm.functions.Function<N>) and the link from such a supertype leads to a non-existing page.

Expected behaviour
A function supertype should be rendered as a functional type, the same way functional parameters are rendered.

Screenshots

The interface is defined as public expect interface KProperty0<out V> : KProperty<V>, () -> V, but rendered as:

And the Function0<V> link leads nowhere.

Instead, I would expect something like:
