Migrates Flutter iOS apps to be compatible with UIScene lifecycle by migrating the AppDelegate and Info.plist. If the AppDelegate does not match Flutter's original template exactly, or if the Info.plist is not found or can't be updated, then prompt the user to migrate manually.

This is hidden behind a feature flag so we can test it out first.

Fixes #170167.

Code Review

This pull request introduces an automated migration tool for iOS apps to adopt the UIScene lifecycle, a necessary update for compatibility with upcoming iOS versions. The changes are well-structured behind a feature flag and include updates to AppDelegate, Info.plist, and the build process. I've identified a critical issue in one of the template files that could lead to invalid Info.plist files, a high-severity issue with a hardcoded license string that could cause migration failures, and a couple of medium-severity issues in the migration logic and tests. Overall, this is a valuable addition, and with these fixes, it will be a solid improvement.
