Generate reference to existing class for builtin function references

Instead of non-existing `kotlin.KotlinPackage`, which led to
NoClassDefFoundError as soon as reflection tried to call getOwner on a
builtin callable reference, use a reference to a new physical class
`kotlin.jvm.internal.Intrinsics$Kotlin`. This will allow to support
KT-17151.

Note that for API version less than 1.4, this will still lead to
NoClassDefFoundError, but this is not worse than the current situation
where it happens anyway.
