RFR: 8373718: jdk/internal/misc/VM/RuntimeArguments.java test fails in Virtual threads mode [v3]

[Brent Christian]

> `RuntimeArguments.java` runs with `@requires vm.flagless`, though setting the `test.thread.factory=Virtual` system property with `-D` will still run the test.
> 
> The test spawns java processes, checking for particular, exact sets of runtime options (hence, `vm.flagless`). It is not expecting to find `-Dtest.thread.factory=Virtual`.
> 
> It doesn't seem important that this test be run with the virtual thread factory. The suggestion of adding this test to `ProblemList-Virtual.txt`  seems reasonable. (It would be a long term resident of the problem list, which is perhaps a bit strange.)
> 
> Alternative courses of action:
> * Teach the test itself to artificially pass in the presence of `-D` options.
> * Enhance the test so it knows how to expect `-D` options; offhand that doesn't seem worth it.
> 
> Update:
> The bots don't like having the "current" bugid present in the problem list. I have updated the bugid in the PL to 8309303 (when the `VM_OPTIONS` constant was added to the test) - a bit disingenuous. If we're not happy with this, I guess a new issue could be filed ("RuntimeArguments.java doesn't account for -D system properties") to use in the problem list.
