feat(Core/Hooks): Add the KillRewarder reference to the OnRewardKillRewarder hook. (#18290)

* Another hackfix attempt at warden payload forcechecks ban fix.

* Revert last commit, interrupt all forcechecks instead of just _dataSent ones.

* Add rewarder parameter to OnRewardKillRewarder hook.

* Undo old warden changes.

* Removed too much!
