RFR: JDK-8313251: Add NativeLibraryLoad event [v5]

[Matthias Baesken]

> Add a NativeLibraryLoad event that provides us more detail about shared lib/dll loads. This gives a time stamp and success + error details of the load operation. It enhances the already existing information we get from the existing NativeLibrary event (that periodically samples the native modules of the jvm process).
