[crac] RFR: Provide arguments for restore [v3]

[Anton Kozlov]

> This change adds a new API and implementation to receive a new set of command-line arguments in the restored Java instance. The supplied demo code shows a faster replacement for `javac`.
> 
> The current implementation obligates the first argument of the new set not to start with the dash, otherwise, the java launcher will interpret it as its own parameter. So the first argument should be a "verb" similar to the Main class.
