[runtime] Initial step towards switching Execution::Call to callable.

Currently Execution::Call (and friends) still duplicate a lot of the
Call sequence logic that should be encapsulated in the Call and
CallFunction builtins. So the plan now is to switch Execution::Call
to accept any Callable and just pass that through to the Call builtin.
