RFR: 8343977: Convert java/awt/TextArea/TextAreaCursorTest/HoveringAndDraggingTest to main

[Tejesh R]

The test is supposed to be problem listed on macos & Linux but the Problem list points to the .java file instead of the .html file.
Hence converting java/awt/TextArea/TextAreaCursorTest/HoveringAndDraggingTest to main which would automatically resolve the issue.
