RFR: 8314838: 3 compiler tests ignore vm flags [v2]

[Evgeny Nikitin]

> For the compiler tests in question this PR:
> 
> - replaces all calls to `ProcessTools.createJavaProcessBuilder` with another method, the `createTestJvm`, which prepends given arguments with what was passed to the enclosing test. The change therefore...
> - makes sure the external arguments aren't ignored and are used for creating the inner JVM;
> - adds `@requires` guards in some places - where the test explicitly controls the Tiered Compilation, for example.
> 
> Testing: a local and a CI run, no failures registered.
