Add GtkWindowControls
Move some code out of GtkHeaderBar and into a separate widget, making it
reusable in process.

+ * SECTION:gtkwindowcontrols
+ * @Short_description: A widget displaying window buttons
+ * @Title: GtkWindowControls
+ * @See_also: #GtkHeaderBar
+ *
+ * GtkWindowControls shows window frame controls, such as minimize, maximize
+ * and close buttons, and the window icon.
+ *
+ * #GtkWindowControls only displays start or end part of the controls (see
+ * #GtkWindowControls:pack-type), so it's intended to be always used in pair
+ * with another #GtkWindowControls using the opposite pack type, for example:
+ *
+ * |[
+ * <object class="GtkBox">
+ * <child>
+ * <object class="GtkWindowControls">
+ * <property name="pack-type">start</property>
+ * </object>
+ * </child>
+ *
+ * ...
+ *
+ * <child>
+ * <object class="GtkWindowControls">
+ * <property name="pack-type">end</property>
+ * </object>
+ * </child>
+ * </object>
+ * ]|
+ *
+ * # CSS nodes
+ *
+ * |[<!-- language="plain" -->
+ * windowcontrols
+ * ├── [image.icon]
+ * ├── [button.minimize]
+ * ├── [button.maximize]
+ * ╰── [button.close]
+ * ]|
+ *
+ * A #GtkWindowControls' CSS node is called windowcontrols. It contains
+ * subnodes corresponding to each title button. Which of the title buttons
+ * exist and where they are placed exactly depends on the desktop environment
+ * and #GtkWindowControls:decoration-layout value.
+ *
+ * When #GtkWindowControls:empty is %TRUE, it gets the .empty style class.
