contracts: Refactor the exec module (#8604)

Browse Source 
* contracts: Add default implementation for Executable::occupied_storage()

* contracts: Refactor the exec module

* Let runtime specify the backing type of the call stack

This removes the need for a runtime check of the specified
`MaxDepth`. We can now garantuee that we don't need to
allocate when a new call frame is pushed.

* Fix doc typo

* Review nits

* Fix defect in contract info caching behaviour

* Add more docs

* Fix wording and typos
