Remove state balance cache (#11964) 
* Remove state balance cache

* remove unused metrics

* add missing balance update

* add comment about locks

* update balance only when updataing the justified checkpoint on unrealization

* update checkpoint balances at launch

* fix unit tests

* fix remaining test

* review

* fix build file

* fix test
