ci: Use xcrun for crash UI test

[philipphofmann]

XCTest isn't built for crashing during tests. Instead of using XCTest to press a button and let a test app crash, we now use UserDefaults to tell the test app to crash during launch. We then simply launch the app again and wait to see if it keeps running. This is basically the same as the testCrash of the SwiftUITestSample without using XCTests.

The plan is to also replace the ui_critical_tests_ios_swiftui_envelope with this approach if this looks acceptable.

I still need to use Xcodegen for the test project and refine the script a bit so it's more reliable.

I think this looks great, exactly what I had in mind re: #5422

If we wanted to have more control of the app we could start a HTTP server in the app being tested and make requests to it from the test host. This is what we do in FaultOrdering and in general is a pattern we've used a lot at emerge. The idea to use user defaults is great though! So much simpler for something like this. Thanks @philipphofmann !
