[iOS/macOS] Add Xcode error if dev dependencies are incorrect (#165916)
Recently, the Flutter tool was updated to remove dev dependencies for
release builds and add dev dependencies for debug/profile builds.

However when building from Xcode directly, dev dependencies are not
enabled/disabled. As a result, it was possible for debug builds to not
have dev dependencies (or vice versa). Example:

1. `flutter build ios --release` - Release build using Flutter tool.
Disables dev dependencies
2. `open ios/Runner.xcworkspace` - Open the iOS project in Xcode
3. In Xcode, **Product** > **Build** - Do a debug build

Previously, step 3 would result in debug artifacts that are missing dev
dependencies. This PR now makes this an error:

## Implementation

The Flutter tool now writes a `FLUTTER_DEV_DEPENDENCIES_ENABLED` in the
generated config file. This tracks whether the currently generated
project has dev dependencies.

In the Xcode build:

1. The Xcode backend script passes the
`FLUTTER_DEV_DEPENDENCIES_ENABLED` config to `flutter assemble` using
the `DevDependenciesEnabled` define
6. The new `CheckDevDependencies` target verifies dev dependencies:
1. It checks if the dev dependencies status is correct for the current
build mode
2. It checks whether the app has dev dependencies by reading the
`.flutter-plugins-dependencies` file. If the app has no dev
dependencies, the error is suppressed.
