clientlibs: Deleted JPopupMenu tests
The following tests are deleted as they don't hold value without SM
test/jdk/javax/swing/JPopupMenu/6691503/bug6691503.java - It tests that the popup are
always-on-top for apps which doesn't hold value after SM removal.

test/jdk/javax/swing/JPopupMenu/6694823/bug6694823.java - Tests whether popup can overlap taskbar.
Works differently on macOS and windows & linux but this is the expected behavior.
Details in JDK-8342012. Not a functional issue.
