mesa: add APPLE_vertex_array_object stubs

APPLE_vertex_array_object support was removed in 7927d0378f.
However it turns out we can't remove the functions because this
can cause issues when libglapi is used together with DRI
drivers built prior to said commit

Fixes: 7927d0378f ("mesa: drop APPLE_vertex_array_object support")
