[Android] OnApplicationPause() is triggered when an activity window is being opened or closed
Reproduction steps:
1. Open the user's attached "HelloWorld.zip" project
2. Open the "MainScene" Scene
3. Go to Assets > Google Mobile Ads > Settings > Google Mobile Ads ID
4. Add "ca-app-pub-3940256099942544~3347511713" as the App ID to the Android field
5. Build and Run for Android
6. Make sure there is an internet connection on the device
7. In the Build, press the "Request AppOpen Ad" button
8. Press the "Request Rewarded Ad" button and wait a few seconds
9. Press the "Show Rewarded Ad" button
10. After the advertisement ends close it
11. Observe the Build
Expected result: OnApplicationPause(false) doesn't get triggered, and the "AppOpen" ad is not shown
Actual result: OnApplicationPause(false) gets triggered and the "AppOpen" ad is shown

Resolution Note:
After some investigation, we have found that Android OS makes a call to onPause when an ad is played, as another activity (the ad) is in focus instead of the main application window. See Android doc: https://developer.android.com/reference/android/app/Activity.
This is how Android OS behaves and Unity reacts to this by invoking OnApplicationPause() to be true when the application window is covered by another activity. The doc https://docs.unity3d.com/ScriptReference/MonoBehaviour.OnApplicationPause.html may need to be updated to reflect this, which we are looking into.
If user would like the pausing to not occur, the suggestion is to override onPause in the activity class in their project, which allows the user to decide when exactly to pass this callback to Unity.
