RFR: 8349953: Avoid editing AOTConfiguration file in "make test JTREG_AOT_JDK=true" [v3]

[Ioi Lam]

> When running HotSpot jtreg tests in the "AOT mode", for example:
> 
> 
> make test JTREG_AOT_JDK=true open/test/hotspot/jtreg/runtime/stringtable
> 
> 
> Before this PR, in the test set up phase, we record several AOT configuration files by running a few separate Java tools (javac, javap, jlink, and jar), and then combine them together with sed, grep, sort and uniq:

> 
> After [JDK-8348426](https://bugs.openjdk.org/browse/JDK-8348426), the AOT configuration file will change to a binary format and can no longer be edited this way. In preparation for [JDK-8348426](https://bugs.openjdk.org/browse/JDK-8348426), we should change the "JTREG_AOT_JDK=true" set up to run a single Java program that accomplishes the same effect as the current implementation.
> 
> ** Changes in this PR **
> 
> This PR combines the invocation of these Java tools into a single Java program, so we just have a single AOT configuration file. It also uses the `-XX:ExtraSharedClassListFile` option to include the default classlist from the JDK home directory,
