DropSite example: handle application/x-color
Show the color that is dragged in, both graphically and textually.
Revert to default palette for other data types. Prioritize colors
over text: if an application (such as kolourpaint) offers both x-color
and text, the color is probably the intention, and the text may be
just a hex string for placing into a color text field.
Pick-to: 6.8 6.9
Fixes: QTBUG-134313
