<AWT Dev> [12] Review Request: 8211822 and 8202886

[Sergey Bylokhov]

Hello.
Please review the fix for jdk12.

Bug: Some tests fail after JDK-8210039
      https://bugs.openjdk.java.net/browse/JDK-8211822
Bug: [macos] Test java/awt/MenuBar/8007006/bug8007006.java fails on MacOS
      https://bugs.openjdk.java.net/browse/JDK-8202886
Webrev: http://cr.openjdk.java.net/~serb/8211822/webrev.00

These tests use the ExtendedRobot which is located in the library, but the fix for JDK-8210039 changed the path to the library, since it assumed only OSInfo was used there, and it missed ExtendedRobot. As a fix the "/test/jdk/lib/testlibrary/" library was added back.

One of the test above fails, because of JDK-8202886, the root cause is the using of the shortcuts to iterate the global menu, which are not necessary configured or might be changed. As a fix the test will use mouse clicks.
