Add EntityExtinguishEvent

[aurorasmiles]

Closes #5143
Replaces #5144
I tried to see if I could manage to fix that issue and add that event. After finishing, I noticed that there already way a PR for this, but as it was made by Ivan and he is banned from the Org, I figured to open a PR anyway.
I haven't implemented cancellable, because I figured this would cause a lot of issues in the long run, and I wasn't sure how to properly address that.
Other than that there is another extinguish called in EntityHuman line 1211, but I decided to not call the event there, since the entity was never technically on fire

Changed :)

One note, otherwise LGTM. The note can be handled on merge.

Don't indent

Do you mind separating the extinguish cases a bit more, please? The previous PR had 8 cases versus 4 in this one.
That would make my life easier 😅
Like for the cauldron, I'd otherwise have to use the CauldronLevelChangeEvent with ChangeReason.EXTINGUISH and getEntity(), and that may be way easier with ths merged.
(or listen for this and check if the entity is inside the cauldron, and if it has water (which may not work since changeLevel() is called before extinguishing, so there will be no water for the lowest water level?))
I'd use that for my temperature module where I trigger some additional effects upon extinguish (different for every case).

Added more reasons, removed the indents and resolved conflicts

"rebased"

Looks good apart from the unused BUBBLE cause.

Nitpick: I would specify what "burning" and "being extinguished" means. Meaning that I would add JavaDoc links to the fireTicks property.

[yannicklamprecht]

I think that isn't needed.

As mentioned in #5517, I think if this pull request want to include 'FireTickChangeEvent' event stuff, then its event name should be altered, so that that event can include both onFire(from 'FireTickChangeEvent'), onExtinguish(from 'EntityExtinguishEvent'). Just food for thought.
