Add GtkIconProvider

This is a minimal interface to provide icon lookup by name.
It is implemented by GtkIconTheme, but platform libraries or
applications can provide their own implementation and pass it
to GTK.

-## Custom Properties
-
-GTK supports custom properties as defined in the
-[CSS Custom Properties for Cascading Variables](https://www.w3.org/TR/css-variables-1)
-spec.
-
-Custom properties are defined as follows:
-
-```css
---prop: red;
-```
-
-and used via the `var` keyword:
-
-```css
-color: var(--prop);
-```
-
-Custom properties can have a fallback for when the referred property is invalid:
-
-```css
-color: var(--prop, green);
-```
-
 ## Colors
 
 GTK extends the CSS syntax with several additional ways to specify colors.
