Please review the fix for jdk 12.

Bug: https://bugs.openjdk.java.net/browse/JDK-8170937
Webrev: http://cr.openjdk.java.net/~serb/8170937/webrev.00

The logic to calculate the screen insets is changed in the 
XToolkit.java. Please take a look to the comments of the bug for more 

  - Additional sanity checks are added to the "ScreenInsetsTest" test.
  - "FrameBorderCounter.java" is updated because it is used by a few 
tests which starts to fail after the fix in the multi-screen config(it 
fail in single screen config before), the reason is that it opens the 
windows to fast.

Best regards, Sergey.
