Android: Fixes #6732: Don't reload the application on screen rotation

[personalizedrefrigerator]

Summary

• This PR replaces android:configChanges with its value in a new-from-template react-native project. On my tablet, this resolves Android: Note screen/settings screen resets on screen rotation change #6732.
• The space-to-tab conversion on several lines is the result of opening AndroidManifest.xml in Android Studio.

Testing plan

(On Android)

1. Deploy a copy of the app from AndroidStudio
2. Open a note
3. Enter edit mode
4. Rotate the screen

On origin/dev: On my tablet, after step 4, the app exits edit mode and scrolls to the top of the note (the app is partially reloaded). With this PR, the app stays in edit mode.

Do you understand the reason why these parameters fix the issue? If so could you add a comment above the "android:configChanges" line please?

I'm not entirely sure why these changes fixed the issue. I just tested laurent22/dev on an Android emulator and am not experiencing the issue. I think my (Samsung) tablet might be configured to treat orientation changes as window resizes.

According to the above links, screenLayout and smallestScreenSize are for multi-window/split screen layout changes. My tablet was operating in single-window mode.

I'm not entirely sure why these changes fixed the issue.

From https://developer.android.com/guide/topics/manifest/activity-element

android:configChanges
Lists configuration changes that the activity will handle itself. When a configuration change occurs at runtime, the activity is shut down and restarted by default, but declaring a configuration with this attribute will prevent the activity from being restarted. Instead, the activity remains running and its onConfigurationChanged method is called.

I don't see how smallestScreenSize is relevant but having it won't hurt I guess
