RFR: 8319343: Improve CDS module graph support for --add-modules option [v2]

[Calvin Cheung]

> Summary of changes:
> 
> Before dumping info the archive, all the module names from `--add-modules` will be sorted and then concatenated into one string with comma as the separator between module names.
> 
> During runtime, same function will be used to obtain the string in the same format with sorted module names. The string will be compared with the one from the archive to determine if the same module names were specified during dump time.
> 
> ModuleBootstrap.java
>         The `addModulesFromRuntimeImage` method is added to check if the modules in `addModules` are from the runtime image. If any of the modules isn't in the runtime image, archiving will be disabled.
> 
> ArchivedModuleGraph.java
>        The constructor has an addition argument `Set addModules`
>        The `get` method also has an addition argument `Set addModules`. It returns the `archivedModuleGraph` only if both the `mainModule` and the `addModules` are the same as the input arguments.
> 
> Passed tiers 1 - 4 testing.
