Use tracing for explosions (#4845)

* TNT: Implement tracing algorithm

+ Add intensity tracing
* Fix iterating over all players to SendExplosion, even those not in range

* Implemented TNT entity interaction

* Fixed misaligned destruction tracing

* Finalise TNT algorithm

- Remove BlockArea and just use chunks

Using SetBlock makes it so that we can update everything properly, and does appear to be faster.

* BlockInfo learns about explosion attentuation

* Rename Explodinator parameters

* TNT: pull block destruction into common function
