[jdk11u-dev] RFR: 8210039: move OSInfo to top level testlibrary

[Goetz Lindenmaier]

I want to backport this test cleanup as it simplifies later backports.

Stuff to resolve was all trivial.

Already fixed:
patching file test/jdk/java/awt/Choice/PopupPosTest/PopupPosTest.java
patching file test/jdk/java/awt/FileDialog/8003399/bug8003399.java

Resolved because html test was already removed
test/jdk/java/awt/KeyboardFocusmanager/ConsumeNextMnemonicKeyTypedTest/ConsumeNextMnemonicKeyTypedTest.java
test/jdk/java/awt/KeyboardFocusmanager/TypeAhead/SubMenuShowTest/SubMenuShowTest.java
test/jdk/java/awt/List/FirstItemRemoveTest/FirstItemRemoveTest.java
test/jdk/java/awt/List/KeyEventsTest/KeyEventsTest.java
test/jdk/java/awt/datatransfer/MissedHtmlAndRtfBug/MissedHtmlAndRtfBug.java
