Original issue's description:
> Implements CSSPropertyAPI for the margin properties.
> 
> A part of Project Ribbon, separating the parsing logic for CSS
> properties from the parser into an API. This patch removes
> CSSPropertyMargin{Top,Right,Bottom,Left},
> CSSProperty{Top,Right,Bottom,Left}, and
> CSSPropertyWebkitMargin[Top|Right|Bottom|Left] from the switch statement
> in parseSingleValue, and calls the API instead.
> 
> A function pointer to the parseSingleValue function from the API for the
> margin properties is stored in a CSSPropertyDescriptor, and is
> called from CSSPropertyParser.
> 
> This patch:
> - Adds CSSPropertyAPIMargin.cpp and CSSPropertyAPIWebkitMargin.cpp to
>   the BUILD.gn file.
> - Adds api_class=CSSPropertyAPIMargin and
>   api_class=CSSPropertyAPIWebkitMargin flag in CSSProperties.in to each
>   of the margin and -webkit-margin properties respectively, which
>   indicates that CSSPropertyAPIMargin.h and CSSPropertyWebkitMargin.h
>   are generated.
> - Moves the parsing logic for radius from CSSPropertyParser.cpp
>   to CSSPropertyAPI[Webkit]Margin.cpp, which implements CSSPropertyAPI.h.
