Adding @sammy-SC as he is most familiar with measure and this would probably need to be reflected in fabric as well. |

Summary
On Android, when using split-screen mode, the Window-relative position of a native View is not calculated properly when the app is running on the right (or bottom) half of the screen. The coordinates are currently calculated only based on View.getLocationOnScreen() with subtracting status bar height. Scenarios, where the window does not fill the entire screen (such as split-screen mode) are not supported.
We need to use a more general solution to subtract the actual position of the window from position of the view within the screen. This PR fixes the issue by subtracting coordinates of the Window retrieved from View.getWindowVisibleDisplayFrame(), which covers all scenarios when Window can be in a different position than the screen (incl. status bar offset).
