Allows code to directly use GS::Vertex for their own purposes without having to rely on GS::VertexBuffer, which comes with the added overhead of allocating GPU memory.
Changes the GS::VertexBuffer storage to be one continuous buffer that is properly aligned and is also now used for GS::Vertex. This halves the necessary memory, removes reallocation cost and removes the copy necessary to get things onto the GPU.

The previous fix unfortunately didn't actually fix it and instead made the crash invisible at first and then corrupt the heap at a later point. With this, VS2013 and VS2015 create code identical to what VS2017 creates, and no longer seem to crash.
