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

* Fix linting

* Fix evmbin compile

* Fix unconfirmed_substate and static_flag

* Fix an issue in create address logic

* Fix top-level tracing

* Handle builtin tracing

* Fix suicide and reward tracing index stack

* Fix an issue where trap conflicts with tracing

* Fix an issue in parent step vm tracing

* Fix revert tracing

* Fix evmbin tests

* Remove params clone

* Fix TODO proofs
