Add test annotations required to run the test suite on iOS (PEP 730). The majority of the change involve annotating tests that use subprocess, but are skipped on Emscripten/WASI for other reasons, and including iOS/tvOS/watchOS under the same umbrella as macOS/darwin checks. `is_apple` and `is_apple_mobile` test helpers have been added to identify *any* Apple platform, and "any Apple platform except macOS", respectively.
