<i18n dev> RFR: 8366178: Implement JEP 526: Lazy Constants (Second Preview) [v3]

[Per Minborg]

> Implement JEP 526: Lazy Constants (Second Preview)
> 
> The lazy list/map implementations are broken out from `ImmutableCollections` to a separate class.
> 
> The old benchmarks are not moved/renamed to allow comparison with previous releases.
> 
> `java.util.Optional` is updated so that its field is annotated with `@Stable`.  This is to allow `Optional` instances to be held in lazy constants and still provide constant folding.
