Break circular dependency between Client and Engine (part 1) (#10833) 

* First draft: pass the parent block header to on_close_block

* typos and cleanup

* whitespace

* Store parent in ClosedBlock as well so it can be reopen()'d

* Don't pass parent when reopening a block

* Remove the unused ancestry param
