Handle methods descriptor clash in data class

1. Extension functions declared in data classes are generated earlier by `generateMembersDeclaredInClassBody` 2. Extension functions fake override from parent class are generated earlier by `generateFakeOverrideMemberDeclarations` So it is safe to filter out extension functions inside `generateAdditionalMembersForDataClass` #KT-49715 #KT-51798
