vmtestbase nsk/jdi tests run 2 processes: debugger and debugee. There is not need to start debugger in the separate process for each test. Also, no need to run it with "-Xcomp" because the main goal is to test debugee behavior with different VM flags. This fix updates tests to run debugger as driver to optimize execution time. The fix also eliminates System.exit() which is not compatible with driver/agentvm mode and update shared classes to correctly add classpath when running debugee. There were few tests which still execute using othervm mode. They require some specific classpath/settings. Tested by running all tests, with '-Xcomp' and virtual thread test factory.
