[GL]Capabilities*: Enhance identity-check in root Capabilities.equals(..), comparing the VisualID first; Added VisualIDHolder.isVisualIDSupported(VIDType)

We cannot accept 2 capabilities with different VisualID but same attributes otherwise accepted as equal,
since the underlying windowing system uniquely identifies them via their VisualID.

Such comparison is used in certail GLAutoDrawable implementations like AWT GLCanvas
to determine a configuration change etc.
