[crac] RFR: 8365241: [CRaC] Ignore new arguments when CRaCIgnoreRestoreIfUnavailable is true [v2]

[Timofei Pushkin]

> Arguments are not passed to the restored process when `-XX:+CRaCIgnoreRestoreIfUnavailable` is set on restore. The check is performed on the side of the restoring VM since in the restored VM `CRaCIgnoreRestoreIfUnavailable` could have been set before the current restore.
> 
> Documentation for the new arguments feature and `CRaCIgnoreRestoreIfUnavailable` is also added, explaining this behavior.
