Reland 105087: PrintPreview: Fix printer color settings issues based …

…on printer ppd/schema info.

Show/Hide the color options based on printer ppd/schema information. Some printers does not provide sufficient information in the printer schema/ppd regarding the color settings and they use custom advance settings to print in black & white/greyscale. In those cases, users need to print using native dialog in order to set these advance color settings.
