[C] Add missing EntityDamageEvents. Adds BUKKIT-3684, BUKKIT-1944

#### The Issue:
Currently, no EntityDamageEvent is fired when Blazes, Squids, or Enderman are drowning.

#### Justification for this PR:
This event is fired under the same circumstances for Snowmen. It only makes sense that one should be fired here as well.

#### PR Breakdown:
This PR adds a call to EntityDamageEvent when Blazes, Squids, or Enderman are drowning.
