core/state: remove account reset operation v2 (#29520)

* core/state, tests: remove account reset operation

* core/state, core/vm: implement createcontract journal event

* core/state: make createcontract not emit dirtied account, unskip tests

* core/state: add createcontract to journal fuzzing

* core/state: fix journal

* core/state: address comments

* core/state: remove useless code
