use VAO in VertexManager

to use VAO, we must use VBO, so some legency code was removed:

- ARB_map_buffer_range must be available (OGL 3.0), don't call glBufferSubData if not
- ARB_draw_elements_base_vertex also (OGL 3.2), else we have to set the pointers every time
- USE_JIT was removed, it was broken and it isn't needed any more

And the index and vertex buffers are now synchronized, so that there will be one VAO per
NativeVertexFormat and Buffer.
