When a test depends on a new debugserver feature/fix, the API test must be marked @skipIfOutOfTreeDebugserver because the macOS CI bots test using the latest Xcode release debugserver. But over time all of these fixes & new features are picked up in the Xcode debugserver and these skips can be removed. We may see unexpected test failures from removing all of these 1+ year old skips, but that's likely a separate reason the test is failing that is being papered over by this skip.
