Kotlin 1.7.20 added optimizations for delegated properties on the JVM,
which broke serialization for optimized properties. Commit bfeff81
tried to fix that, but broke non-optimized delegated properties. This
commit restores correct serialization for optimized and non-optimized
properties, also ensuring that it only affects the JVM target.
#KT-58954 Fixed
#KT-59113 Fixed
Do not include delegated field into generated constructor even though it
might have backing field.
Test that shows issue was added. Properties that are explicitly marked
as delegated are now excluded.
