[crac] RFR: 8364662: [CRaC] Process restore options in the common arguments parser [v3]

[Timofei Pushkin]

> Options for restore are now processed during the common VM arguments parsing stage.
> 
> Notable improvements compared to the old code:
> - Options from `-XX:Flags=<file>` and `-XX:VMOptionsFile=<file>` are now also considered
> - Option aliasing is now handled correctly
> 
> **Behavioral change**. If `CRaCIgnoreRestoreIfUnavailable` is true it is now not an error to specify non-restore-settable options on restore — these will just be omitted from forwarding to the restored JVM. This makes it possible to specify non-restore-settable to be used after a failed restore.
