RFR: 8321713: Harmonize executeTestJvm with create[Limited]TestJavaProcessBuilder

[Stefan Karlsson]

[JDK-8315097](https://bugs.openjdk.org/browse/JDK-8315097): 'Rename createJavaProcessBuilder' changed the name of the ProcessTools helper functions used to create `ProcessBuilder`s used to spawn new java test processes.

We now have `createTestJavaProcessBuilder` and `createLimitedTestJavaProcess`. The former prepends jvm options from jtreg, while the latter doesn't.

With these functions it is common to see the following pattern in tests:

ProcessBuilder pb = ProcessTools.createTestJavaProcessBuilder(...);
OutputAnalyzer output = executeProcess(pb);


We have a couple of thin wrapper in `ProcessTools` that does exactly this, so that the code can be written as a one-liner:

OutputAnalyzer output = ProcessTools.executeTestJvm();


I propose that we name this functions using the same naming scheme we used for `createTestJavaProcessBuilder` and `createLimitedTestJavaProcessBuilder`. That is, we change `executeTestJvm` to `executeTestJava` and add a new `executeLimitedTestJava` function.
