This removes the take_ownership parameter and defines the behavior as if
take_ownership was always true, which is the fast path. This way, we don't
have to have 2 codepaths in set_vertex_buffers of every driver.
The old behavior is optionally available through util_set_vertex_buffers.
It also documents a new constraint that count in set_vertex_buffers must be
equal to the number of vertex buffers referenced by vertex elements or 0.
