mesa: Update VAO internal state when setting the _DrawVAO.

Update the VAO internal state on Array._DrawVAO instead of
Array.VAO. Also the VAO internal state update gets triggered now
by a change of Array._DrawVAO instead of the _NEW_ARRAY state flag.
Also no driver looks at any VAO's NewArrays value from within
the Driver.UpdateState callback. So it should be safe to move
this update into the _mesa_set_draw_vao method.
