`mustache_template` was moved to flutter/core-packages, but I didn't realize that `google_fonts` uses it in its generator. Now that it's not in-repo, that requires an explicit allowance so that pubspec validation passes.

instead of generating
```swift
enum FooEnum: Int {
  case foo = 0
  ...
```
we will now generate
```swift
enum FooEnum: Int, CaseIterable {
  case foo = 0
  ...
```
allowing consumers to use `FooEnum.allCases` to iterate over all possible enum values in swift platform code

fixes flutter/flutter#186447

**Note**: The Flutter team is currently trialing the use of [Gemini Code Assist for GitHub](https://developers.google.com/gemini-code-assist/docs/review-github-code). Comments from the `gemini-code-assist` bot should not be taken as authoritative feedback from the Flutter team. If you find its comments useful you can update your code accordingly, but if you are unsure or disagree with the feedback, please feel free to wait for a Flutter team member's review for guidance on which automated comments should be addressed.

[^1]: Regular contributors who have demonstrated familiarity with the repository guidelines only need to comment if the PR is not auto-exempted by repo tooling.

[camera_web] Fix facingMode capability handling

Fixes flutter/flutter#174985

Prevents `availableCameras()` from throwing a TypeError when a browser returns an invalid `facingMode` capability. The plugin now treats invalid or missing facing mode capabilities as unavailable, allowing `availableCameras()` to continue and fall back to `CameraLensDirection.external`.

Tests:
- `dart format packages/camera/camera_web/lib/src/camera_service.dart packages/camera/camera_web/example/integration_test/camera_service_test.dart`
- `flutter analyze`
- `flutter test`
- `flutter drive --release --driver=test_driver/integration_test.dart --target=integration_test/camera_service_test.dart -d chrome`
- `flutter drive --release --driver=test_driver/integration_test.dart --target=integration_test/camera_web_test.dart -d chrome`
