Plugin linking fails using local engine: Flutter.framework/Flutter, building for iOS-arm64 but attempting to link with file built for iOS Simulator-x86_64 #51989
Description
Similar to #50568 but for plugins when building with a non-fat local engine (only x86 or only arm)
ld: warning: ignoring file /Users/m/Downloads/app5/ios/Flutter/Flutter.framework/Flutter, building for iOS-arm64 but attempting to link with file built for iOS Simulator-x86_64

The plugin targets run before the app target, so it fails before xcode_backend can run and copy the right version of Flutter.framework at FRAMEWORK_SEARCH_PATHS = $(inherited) "${PODS_ROOT}/../Flutter".
