[jdk11u-dev] RFR: 8211999: Window positioning bugs due to overlapping GraphicsDevice bounds (Windows/HiDPI) [v2]

[Martin Doerr]

> Backport of JDK-8211999. Applies almost cleanly. I had to integrate hunks in WRobotPeer.java and Robot.java manually.

Martin Doerr has updated the pull request incrementally with two additional commits since the last revision:

 - Adapt WindowSizeDifferentScreens.java to jdk11.
 - Move useAbsoluteCoordinates() down where it better matches upstream version
