Don't mutate a NinePieceImage to create a mask default image
https://bugs.webkit.org/show_bug.cgi?id=202967

Reviewed by Dean Jackson.

For every StyleRareNonInheritedData, the maskBoxImage undergoes copy-on-write
via maskBoxImage.setMaskDefaults(). Fix by giving NinePieceImage a constructor
argument that cna make the mask flavor of image.
