Compare layout handle in vertex-stream rebind gate (#3811)

Browse Source 
The gate compares (handle, startVertex) but not the layout handle, so draws
colliding on startVertex with different-stride layouts wrongly skip the rebind.
Fix hasVertexStreamChanged() and OpenGL's inline copy. Matches #2562.
