This test Mac native_platform_view_ui_tests_ios was newly added to CI, but has been failing consistently. This is consuming bot resources.

One example build: https://ci.chromium.org/ui/p/flutter/builders/staging/Mac%20native_platform_view_ui_tests_ios/91/overview

@hellohuanlin Could you help take a look? Shall we disable it for now?
