This PR turns SwiftPM on by default. This will opt users into SwiftPM and auto-migrate their project if it hasn't already been migrated. Users can still opt-out using these instructions: https://docs.flutter.dev/packages-and-plugins/swift-package-manager/for-app-developers#how-to-turn-off-swift-package-manager

Fixes #151567.

Mac_ios flavors_test_ios is failing, so we'll need to wait for #183011 to land first.

This is ready for review, though.

Code Review

This pull request enables Swift Package Manager (SwiftPM) by default on the master and beta channels. The core change is updating the swiftPackageManager feature flag. The rest of the changes are consequential updates to tests and project files. Tests that rely on CocoaPods now explicitly disable SwiftPM. Other tests are updated to reflect changes in build outputs and error messages. A benchmark project incompatible with SwiftPM is configured to opt-out. The changes appear correct and are well-tested.

When you use SwiftPM, packages also become schemes. So I changed the check to be part of the error that doesn't list the specific schemes

This project couldn't be auto-migrated due to it's weird setup. Migrated manually.
