Move GtkGradient to their own files, also move GtkBorder out of
gtkstyle.h, so that header can be all deprecated.

* @Short_description: Gradients
* @Title: GtkGradient
*
* GtkGradient is a boxed type that represents a gradient.
* It is the result of parsing a
* <link linkend="gtkcssprovider-gradients">gradient expression</link>.
* To obtain the gradient represented by a GtkGradient, it has to
* be resolved with gtk_gradient_resolve(), which replaces all
* symbolic color references by the colors they refer to (in a given
* context) and constructs a #cairo_pattern_t value.
*
* It is not normally necessary to deal directly with #GtkGradients,
* since they are mostly used behind the scenes by #GtkStyleContext and
* #GtkCssProvider.
