RFR: 8358600: Template-Framework Library: Template for TestFramework test class [v3]

[Emanuel Peter]

> We might want to write many IR/TestFramework tests, and so I would like to integrate a Template that generates the class, and the user has to only generate a list of tests.
> 
> This is a first extension for https://github.com/openjdk/jdk/pull/24217. I had already prototyped it earlier and plan to use it in multiple tests https://github.com/openjdk/jdk/pull/23418 (see `IRTestClass.java`).
