Disable Entity Collision without Team

[LeScooter]

At present, the only method to disable collision between entities, such as two players, involves assigning one of the players to a team and updating the team's CollisionRule. This rule is then evaluated by the utility function pushableBy within EntitySelector.java, which is used by LivingEntity to query pushable entities when calling pushEntities.

It would be beneficial to have an official feature through NeoForge that allows setting collision rules directly on an entity without the need to place the entity within a team.
