X11 Fix NativeVisualID regression (commit 90c46b1ef1f199ceb63e85c85e9ebeb919d49c4a) ; Using plain X11 Capabilities

In case X11GLXGraphicsConfigurationFactory and hence X11GLCapabilities (glx) is not being used,
the X11GraphicsConfigurationFactory used plain Capabilities object for the chosen caps.
The latter is not derived from NativeVisualID.

- Added X11Capabilities supporting NativeVisualID to fit our needs.
- X11Capabilities.XVisualIDComparator uses NativeVisualID.NVIDType.X11_XVisualID
- *Capabilities have better unique names in toString()
