When use the method setTargetResolution, the metadata would be lost.

Use the code below to query metadata.
```
val model = ExifInterface(savedUri.toFile()).getAttribute(ExifInterface.TAG_MODEL)
Log.d(TAG, "Photo capture succeeded: model ==> $model")
```

Here is patch.

I found that the metadata lost after `androidx.camera.core.internal.utils.ImageUtil#cropByteArray` called.

Start with CameraXBasic/app/src/main/java/com/android/example/cameraxbasic/fragments/CameraFragment.kt and reproduce the reported metadata lookup after using setTargetResolution. Trace the reported path through androidx.camera.core.internal.utils.ImageUtil#cropByteArray and compare the saved image metadata with the ExifInterface TAG_MODEL result. Done means identifying why metadata is lost and confirming that captured metadata is preserved.
