Allow Mac mac_host_engine tests to run for up to 90 minutes (previously assumed 60) and allow the tests to run on Mac-14. This should give the test more time when it needs to do additional tasks like install Xcode. Timeout was recently added in https://flutter-review.googlesource.com/c/recipes/+/57980. Timeout tested in https://ci.chromium.org/ui/p/flutter/builders/try/Mac%20Engine%20Drone/941415/infra (timeout set to 4 minutes). Fixes https://github.com/flutter/flutter/issues/150011.
