Remove builtin Position/Rotation/Matrix components from core library

[vkensou]

Many engine have there own vector/matrix struct. So embed Position/Rotation/Matrix/etc in core library is unnecessary. We can offer theres component as extensions.

Doing this will break compatibility.
So I don't want to do this at the moment.

Since it's now a preview version, I don't think we need to worry too much about compatibility.

In case changing the mentioned types I would move them to namespace Friflo.ECS.Math.
I let this topic open for better naming suggestions.

I have to place global using Position = ... in every project to resolve name ambiguines with Friflo.Engine.ECS.Position because I have my own Position struct fitting my needs.
