[lworld] [Rev 01] RFR: 8247357: Flattenable field concept needs some cleanup

[Frederic Parain]

> Please review these changes cleaning up the flattenable field concept.
> The concept has evolved with time and now all fields with an inline type are by definition flattenable, so the need to
> have a "flattenable bit" on the side is gone. The changeset contains a mix of renaming and code cleaning. The changes
> don't include JIT code, which would be fix in a follow-up patch.
> Thank you,
>
