[crac] RFR: Support updating MANAGEABLE JVM options during restore [v3]

[Radim Vansa]

> When a JVM option is MANAGEABLE it can be set at any time during runtime, therefore it is safe to change it during the restore operation. Rather than silently ignoring JVM options passed along with -XX:CRaCRestoreFrom we send them to the restored process and either update or print a warning if given option cannot be changed.
