RFR: 8352999: [macOS] Conditional behavior by directly querying the Objective-C call stack

[Martin Fox]

Before a window is maximized glass records its existing size and location. This rectangle is stored in native screen coordinates. Compared to Java screen coordinates native coordinates are flipped along the Y axis.

When the window is un-maximized that native rectangle is passed to a routine that normally takes Java screen coordinates. To determine whether the rectangle is flipped or not the code inspects the Objective-C stack to figure out which routine called it.

At the risk of re-writing working code this PR takes a more conventional approach to the problem.

I’ve also re-enabled the related system test. I had to increase the animation delay to get it to pass on the Mac. 400 milliseconds is enough but 500 gives us some headroom.
