SharedComponentTypeHandle<T> An object representing the type information required to safely access shared component data stored in a chunk.
Manually gets the run-time type information required to access a shared component data in a chunk.
Remember to call SharedComponentTypeHandle<T0>.Update.
Prefer using SystemAPI.GetSharedComponentTypeHandle in SystemAPI as it will cache in OnCreate for you
and call .Update(this) at the call-site.
