> Credit to @lukellmann that the duplication arg handling in #24742 avoided throwing exceptions but produced a wrong option. This patch fixes that and removed stream usages in CaptureCallState to speed up bootstrap.
> 
> Also, the previous patch affected the toString display of the option; I added a unit test to ensure the option prints names that is user-friendly.
> 
> Another thing I noted is `CapturableState` uses `OperatingSystem`; using `valueOf` brings a performance overhead due to setups with reflection, so I made this lazy. (The enum is thread safe, so we allow racy access to the cache field)
> 
> Testing: jdk/lang/foreign, tier 1-3 in progress.
