<AWT Dev> [14] Review Request: 8232200 [macos 10.15] Windows in fullscreen tests jumps around the screen

[Sergey Bylokhov]

Hello.
Please review the fix for JDK 14.

Bug: https://bugs.openjdk.java.net/browse/JDK-8232200
Fix: http://cr.openjdk.java.net/~serb/8232200/webrev.02/

Our code assumes that when the display mode of the screen has changed,
the windows on the screen should not be moved, but on macOS 10.15 these
windows jump around, so we need to set all bounds of the window.

In the fix we will change the bounds of the window in the callback, which
is called when the display mode is actually changed by the application or
by some other reason.

The test is moved from the closed to the open repo.
