Prohibit local objects and enum classes

#KT-5402 Fixed
  #KT-4838 Fixed

Resolve type of object inside local object as special, not supertype('Any').
Changed visibility of constructor of anonymous object to 'internal' to be able to resolve the following:
fun box(): String {
    var foo = object {
        val bar = object {
            val baz = "ok"
        }
    }
    return foo.bar.baz
}
The containing declaration of property initializers is constructor, so 'baz' was invisible inside private constructor.
