[lworld] RFR: 8368988: [lworld] Rename classes in valhalla/inlinetypes to be distinct [v2]

[Marc Chevalier]

> Various cleanup in test package `compiler.valhalla.inlinetypes`:
> - rename duplicated classes so that IDEs are nice, resolve correctly. New names are a bit... arbitrary. I'm happy to rename name if anyone has opinions. When writing new tests, let's prefer nested classes if we can.
> - add `package compiler.valhalla.inlinetypes;` where it was missing. IDEs like that, and I vaguely remember we should.
> - fix flags to take the new path into account, new package, or class renaming. Please, try to pay attention to that: I've did multiple passes to catch'em all, but this is easy to miss.
> - remove some useless `import`.
> - some few typos in comments.
> - maybe more?
> 
> Thanks,
> Marc
