RFR: 8223717: javafx printing: Support Specifying Print to File in the API [v4]

[Phil Race]

> This enhancement adds the String property outputFileProperty() to the JobSettings class.
> The value should be a string that references a local file encoded as a URL.
> If this is non-null and set to a location that the user has permission to write to,
> then the printer output will be spooled there instead of the printer, so long as the platform printing system supports this.
> The user can of course also set a print-to-file destination in the platform printer dialogs which may over-ride what the application set. But now the application can also see what it was set to, and cancel or alter it if necessary.
> 
> A simple manual test is provided, manual mainly because the few real printing functional tests are all manual as they are only useful if run with a printer configured.
