[Bug report] ML Kit Document Scanner should not fix activity orientation to portrait on Android 16/17

**Describe the bug**
`com.google.mlkit.vision.documentscanner.internal.GmsDocumentScanningDelegateActivity` is declared with a fixed screen orientation (`android:screenOrientation="PORTRAIT"`), which causes Play Console to flag the app for large-screen compatibility issues.

As an app developer, I see this warning in Play Console:

> Remove resizability and orientation restrictions in your app to support large screen devices
> From Android 16, Android will ignore resizability and orientation restrictions for large screen devices, such as foldables and tablets. This may lead to layout and usability issues for your users.

Play Console reports the following restricted activities in my app:

```xml

```

We're using `com.google.android.gms:play-services-mlkit-document-scanner:16.0.0`
