mesa: Provide an alternative to get_vp_mode()
To get equivalent information than get_vp_mode(), track the vertex processing mode in a per context variable at gl_vertex_program_state::_VPMode. This aims to replace get_vp_mode() as seen in the vbo module. But instead of the get_vp_mode() implementation which only gives correct answers past calling _mesa_update_state() this context variable is immediately tracked when the vertex processing state is modified. The correctness of this value is asserted on state validation. With this in place we should be able to untangle the dependency with varying_vp_inputs and state invalidation.
