Fix sampling from an external GL texture.

1) GL external texture validation was preventing use of
   TextureUsage::TextureBinding. Fixed by allowing that usage during
   validation.

2) Wrapped external textures were leaving the subresources marked as
   uninitialized, causing them to be cleared on first use. Fixed by
   setting the subresource intialization state from the external
   texture descriptor's "isInitialized".
