RFR: 8207948 : JDK 11 L10n resource file update - msg drop 10

[li.jiang at oracle.com]

Hi,

Please review these changes for JDK 11 L10n resource file update message 
drop 10.

webrev:
http://cr.openjdk.java.net/~ljiang/8207948/webrev/read/open/

bug:
https://bugs.openjdk.java.net/browse/JDK-8207948

Since JDK11, we support only Japanese and Simplified Chinese. This is 
the first message drop for JDK 11 release, so this webrev has the 
updates for the resource files, especially the properties files of jdk 
tools, since JDK 10 released.

One file is new added:
src/jdk.compiler/share/classes/com/sun/tools/javac/resources/launcher.properties

If you add a new resource file into JDK 11 repo, and not find the 
localized version here, pls let me know,

Thanks,
Leo
