Previously, the semantic was more-or-less correct for most of the cases
but some corner one, like `sort` in MutableList didn't work properly.
Namely, `sort` should be marked there in a way to forbid to call it
everywhere beside super-calls.
Also, overriding it should be allowed.
Mostly, the logic was re-written to K2 model from K1-related
JvmBuiltInsCustomizer.
^KT-57694 In progress
^KT-57269 Fixed
Use the same condition as in the already existing `createIrEnumEntry`
function (and as in psi2ir): enum class should be final unless there's
an enum entry with any declaration other than its constructor.
