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

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:

https://github.com/openjdk/jdk/blob/adc3f53d2403cd414a91e71c079b4108b2346da0/make/RunTests.gmk#L723-L744

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,
