This pull request is created by [automatic cherry pick workflow](https://github.com/flutter/flutter/blob/main/docs/releases/Flutter-Cherrypick-Process.md#automatically-creates-a-cherry-pick-request)
Please fill in the form below, and a flutter domain expert will evaluate this cherry pick request.

### Issue Link:
What is the link to the issue this cherry-pick is addressing?

https://github.com/flutter/flutter/issues/157359

### Changelog Description:
Explain this cherry pick in one line that is accessible to most Flutter developers. See [best practices](https://github.com/flutter/flutter/blob/main/docs/releases/Hotfix-Documentation-Best-Practices.md) for examples

Prevents `flutter build ios-framework --xcframework` from copying an extraneous Flutter.xcframework.dSYM into the App.framework folder

### Impact Description:
What is the impact (ex. visual jank on Samsung phones, app crash, cannot ship an iOS app)? Does it impact development (ex. flutter doctor crashes when Android Studio is installed), or the shipping production app (the app crashes on launch)

Previously, `flutter build ios-framework --xcframework` would fail with
`error: Multiple commands produce '......./BuildProductsPath/Release-iphoneos/Flutter.framework.dSYM/Contents'`. 

Is there a workaround for this issue?

The workaround is to delete `App.xcframework/ios-arm64/dSYMs/Flutter.framework.dSYM`.

### Risk:
What is the risk level of this cherry-pick?

### Test Coverage:
Are you confident that your fix is well-tested by automated tests?

### Validation Steps:
What are the steps to validate that this fix works?

Try to build any example app with `flutter build ios-framework --xcframework`, then inspect the App.framework folder. It should only include  `App.framework.dSYM`, and not `Flutter.xcframework.dSYM `
