(Dots) Property attributes not working for IComponentData

These property attributes were designed for UnityEngine.Object serialization system and Dots uses none of that.

But what's more important here - if you ever find yourself constructing huge IComponentData where you even need those attributes just to manage the clutter - you're making a pretty serious technical mistake.

DOD core thesis is that memory layout is important for performance. OOP pretends memory layout doesn't matter. So there is much to unlearn if you wish to succeed with Dots.

• TL;DR: Another IComponentData is your [Header] here. What you need to do is to split all this data in many small, specialized IComponentData.
