VertexBuffer, VertexLayout and GeometryBinding improvements

Browse Source 
- VertexBuffer: Added constructor that takes stride instead of type
- VertexLayout: Added Refcounting to VertexLayout and ownership parameters for VertexElements
- Fixed: GeometryBinding using stride and offset from buffer instead of buffer binding
