(11u) RFR: 8214046: [macosx] Undecorated Frame does not Iconify when set to

[Lindenmaier, Goetz]

Hi,

I want to downport this for parity with 11.0.6-oracle.
I had to do a trivial resolve: one line of context differs.

AWTWindow.m, Line 
       if (IS(styleBits, FULL_WINDOW_CONTENT))  type |= NSFullSizeContentViewWindowMask;
is not there in 11u.

Bug: https://bugs.openjdk.java.net/browse/JDK-8214046
Orig change: http://hg.openjdk.java.net/jdk/jdk/rev/769dbf384c44
Webrev: http://cr.openjdk.java.net/~goetz/wr19/8214046-mac_iconify-jdk11/01/

Best regards,
  Goetz.
