roundedbox: Add gtk_rounded_boxes_init_for_style()

Browse Source 
Instead of making people intiialize a rectangle and then applying border
radius manually, provide a constructor that does it for them.
While doing that, also allow people to instead request the padding box
or the content box.

Refactor all relevant code to use this new constructor.
