RFR: 8349400: Improve startup speed via eliminating nested classes [v2]

[Shaojin Wen]

> During JVM startup, the class KnownOIDs is loaded. KnownOIDs has 10 anonymous classes, which slows down the startup. This PR is to improve KnownOIDs and eliminate unnecessary embedded classes.

> Here's how to reproduce this:
> 
> 
> public class Startup {
>     public static void main(String[] args) {}
> }
> 
> 
> 
> java -verbose:class Startup
