[9] Review Request: 8056298 Separate java.awt.datatransfer from the desktop module

[Sergey Bylokhov]

Hello.
Please review a fix for jdk 9.
In the fix a sun.datatransfer and a java.awt.datatransfer packages were 
moved to the separate module java.datatransfer.
But sun.awt.datatransfer still located in java.desktop. I tested full 
jdk(all modules included) on osx using a jck, and it works without 
problems, at least no new issues were found. But datatransfer area is 
quite unstable after a bunch of the latest fixes.
I still cannot replace java.desktop in modules.xml, because of some 
another dependencies(See comments in the bug)
