Per-app override sandboxing View API to Activity bounds

Some applications assume that they occupy the whole screen and therefore
use the display coordinates in their calculations. This can lead to
shifted or out of bounds UI elements in case the activity is Letterboxed
or is in split-screen mode.

OVERRIDE_SANDBOX_VIEW_BOUNDS_APIS change id forces the packages it is
applied to sandbox View API to Activity bounds for:

android.view.View#getBoundsOnScreen
android.view.View#getLocationOnScreen
android.view.View#getWindowVisibleDisplayFrame
android.view.View#getWindowDisplayFrame

This sandboxing is happening indirectly in android.view.ViewRootImpl through
android.view.ViewRootImpl#getWindowVisibleDisplayFrame,
android.view.ViewRootImpl#getDisplayFrame respectively.

Application developers can opt-out of this treatment by using the
following configuration in their manifest:

<application>
    <property
      android:name=
      "android.window.PROPERTY_COMPAT_ALLOW_SANDBOXING_VIEW_BOUNDS_APIS"
     android:value="false"/>
</application>
