[cogl-vertex-buffer] Add a flush of attribute changes in the *_draw() functions

Browse Source 
For convenience it is now valid to avoid a seperate call to
cogl_vertex_buffer_submit() and assume that the _draw() calls will do this
for you (though of course if you do this you still need to ensure the
attribute pointers remain valid until your draw call.)
