Robert Bragg c86f698eb9 make COGL_FEATURE_VBOS a private feature
Cogl provides a consistent public interface regardless of whether the
underlying GL driver supports VBOs so it doesn't make much sense to have
this feature as part of the public api.  We can't break the api by
removing the enum but at least we no longer ever set the feature flag.

We now have a replacement private feature flag COGL_PRIVATE_FEATURE_VBOS
which cogl now checks for internally.
