1. Add iOS and macOS migration to mark "last upgraded" Xcode version to 14.3 to prevent `Update to recommended settings` warning. 2. Update iOS and macOS templates to same. 3. Update iOS template to set `BuildIndependentTargetsInParallel` to YES as suggested. I didn't add a migration for this since it seems like a minor optimization and I don't think it's worth a potentially botched/corrupted migration. 4. Run all example/integration test project to see migrator work. 5. Add some missing test projects to the build shard since I noticed they were missing and I had to build those manually outside `SHARD=build_tests`. Fixes https://github.com/flutter/flutter/issues/125817 See https://github.com/flutter/flutter/pull/90304 for Xcode 13 example.
