Consistent SpawnEggs

I decided to split the egg sizes more cohesively because it bugged me how the Ender dragon egg was the same size as the cow egg.

Big eggs: Ender dragon, Warden, etc... Medium eggs: Cows, Sheep, etc... Small eggs: Bees, Allays, etc...

Some additional changes I decided to do were

1. Simplification: Some eggs were too busy for their own good, to the point of losing their egg shape.
2. Removed Water Puddle: I don't think they're necessary.
