[Runtime] Factor runtime logic out of CompiledFunction

[gcatron]

With the work on #1904 CompiledFunction and it's inherited forms contain the runtime execution logic. It would be better to keep the function as a container that is acted upon. This would keep logic and storage separate.
Design a runtime API and migrate runtime functionality from CompiledFunction to new API.

One thing to solve while we are here is:
#1599
