<AWT Dev> [9] Review Request: 8032435 Cleanup of sun.awt.windows package

[Sergey Bylokhov]

Hello.
Please review the fix for jdk 9.
This is cleanup of the sun.awt.windows package:
  - Encapsulation strengthening.
  - final and @Override were added whenever possible.
  - WPrintDialog now uses AWTAccessor instead of its own setPeer() 
native method.
