Fix 3c047b1: AIGroup.GetProfitLastYear could get values different than those displayed in GUI (#10227)

* Change: Store "all time" and "since minimum age" last year profits on groups

* Fix: Update last year profit for groups when copying vehicle statistics on autoreplace

* Codechange: Refactor profit last year

* Change: Rename some group related items for clarity

* Change: Reorder the fields in GroupStatistics

That way less memory gets wasted.
