RFR: 8314838: 3 compiler tests ignore vm flags

[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.
