[OpenJDK 2D-Dev] RFR 8154213: clean up uses of boxed primitive constructors in the java.desktop module

[Sergey Bylokhov]

Some tweaks are possible also:
  - In some cases like in PrintServiceLookupProvider.java it is possible 
to use Integer.parseInt() instead of "Integer.valueOf()" + "intValue()".
  - It is also possible to use classes like Integer = GetIntegerAction() 
instead of "String = GetPropertyAction()".
