Resumable EVM and heap-allocated callstack (#9360)
* Add new Vm trappable interface

* Exec/Resume interface

* Basic implementation of CallCreateExecutive

* Implement resume_call and resume_create for executive

* Move convertion to call/create result to separate function

* Implement consume that converts resumable to non-resumable

* Use consume for Executive::call/create
