[Edited] Change the error text for runtime IComponentData

The error message that states that IComponentData types must be known at runtime is missleading and wrong, it can absolutelly be done so long you add those runtime Types before

TypeManager.Initialize()

runs
Currently, to do that you need to:
1 add

UNITY_DISABLE_AUTOMATIC_SYSTEM_BOOTSTRAP

to your player prefs defines as in

2 Then add the

DefaultWorldInitialization.Initialize("Default World", false);

line to after you've created your runtime

IComponentData
