[OpenJDK 2D-Dev] RFR JDK-8246742: ServiceUI.printDialog does not support properties dialog

Actually, I was a bit wrong in construing that the button should just be 
disabled for ServiceUI.printDialog if ServiceUIFactory is null & 
getUI(MAIN_ROLE...) is null.

The "properties" dialog is used for another use-case which is for 
cross-platform dialog also ie, when we have a printer job created using 
(in which case also getUI() will be null for windows)

PrintRequestAttributeSet pSet =new HashPrintRequestAttributeSet();

And, as per JDK-4673406, it  is likely that supporting this 
/"properties" sheet will only be possible where there is already a job 
with which//
//to make the association. ie using 
java.awt.PrinterJob.printDialog(AttributeSet) and not for direct uses 
with javax.print.ServiceUI.printDialog(..)/"

So, ideally, we should be checking if we have a printer job in addition 
to ServiceUIFactory being not null to allow creation of association 
between printer properties and the printer job
so if a PrinterJob cross-platform printer-dialog is created, then we 
should support "Properties" dialog.
If we directly use javax.print.ServiceUI.printDialog(..), then in that 
case no printer job will be created, so properties dialog can be 
disabled for that use-case.
