8302267: [jittester] Improve separation of test generation and execution

[lepestock]

Please review a set of improvements that should improve working with other fuzzing generators and usage of JitTesterDriver with tests generated not by the JITTester:

• Provide better separation of individual test generation from java file writing, compiling, executing, etc.;
• Introduce distinct Phases of the generation process (Generation, Compilation, GoldRun and VerificationRun);
• Extract JItTesterDriver headers generation so that it would be possible to provide other header generators;
• Introduce error tolerance to not get distracted by OOMEs, intrinsics missing in the compiled code, etc.;
• Make it possible to specify time limit for an individual test generation;
• Give better control over temp/workdir creation and cleaning;
• Unify external process running;
• Introduce UTF-8 support in external processes' output and human-readable escaping of it;
