[ci] Add LUCI versions of remaining macOS host tests (#3116)

This continues the LUCI migration of macOS host tests, now that ARM
configurations should be working in LUCI, adding both iOS and macOS
platform tests. In order to reduce later work aligning with
flutter/plugins, this adds the same iOS sharding that is currently used
in flutter/plugins, even though it's overkill for flutter/packages at
the moment.
