[9] Review request for 8130776: Remove EmbeddedFrame.requestFocusToEmbedder() method

[Alexey Ivanov]

Hello AWT team,

Could you please review the following fix:
    bug: https://bugs.openjdk.java.net/browse/JDK-8130776
    webrev: http://cr.openjdk.java.net/~aivanov/8130776/jdk9/webrev.00/
Description:
Cleaning up the unused method. It was added under JDK-8056915 "Focus 
lost in applet when browser window is minimized and restored". Later the 
code has been changed, and this method, requestFocusToEmbedder(), is not 
used any more.

Thanks,
Alexey
