[JVM_IR] Deal with lowering ordering issues for JvmStatic function references.

Do not destructively update the @JvmStatic function, instead
create a copy on first access, and replace the original with
the copy in the jvm static lowering. This ensures that the original
function is seen in other lowerings independently of file lowering
order.
