RFR: JDK-8311511: Improve description of NativeLibrary JFR event

Wed Jul 5 14:46:02 UTC 2023

The JFR NativeLibrary event description should be improved.
Currently there is no description at all, but there should be one indicating that 'NativeLibrary'  can be different kinds of native images.  For example on macOS the frameworks show up.  On AIX,  java itself or some mapped files show up too in the list.

On macOS the 'Top Address'  is currently always 0 (info not available) . So give some hint in the description that this can happen.
