    cogl: Mark vertex buffers as dynamic
    
    Those are cached and reused across runs, which doesn't qualify to mesa
    as "static" indeed. Properly marking those as dynamic is more true, and
    brings in slight performance benefits just by avoiding the resulting
    (and later silenced) mesa warning.
