retry extension does not mesh with TestAbortedException

[Vampire]

Describe the bug

If you use TestAbortedException to conditionally skip a test (either manually, or for example using @PendingFeature or @PendingFeatureIf) and have @Retry effective on that feature (either directly, or from specification, or via some global retry extension) the test is never skipped unless you add the condition { failure !instanceof TestAbortedException } to the retry annotation.

Without that condition and otherwise default setup (depending on extension order, or always when also using mode = SETUP_FEATURE_CLEANUP), the feature throws TestAbortedException, the retry interceptor sees exception and retries, and after retries are through, it throws a MultipleFailuresError with the TestAbortedExceptions inside.

This then causes the iteration to not be skipped, but failed.

Maybe it would be better to either never (maybe configurable) retry for TestAbortedException, or alternatively when it is time to throw the MultipleFailuresError, check (maybe configurable) whether all throwables are TestAbortedExceptions and in that case add all others to the first as suppressed ones and throw the first TestAbortedException so that the result is a skip, not failure.
