Implements CSSPropertyAPI for the transform-origin property.

Implements CSSPropertyAPI for the transform-origin property.

A part of Project Ribbon, separating the parsing logic for CSS
properties from the parser into an API. This patch removes
CSSPropertyTransformOrigin from the switch statement in
parseSingleValue, and calls the API instead.

A function pointer to the parseSingleValue function from the API for the
page property is stored in a CSSPropertyDescriptor, and is called from
CSSPropertyParser.

This patch:
- Adds CSSPropertyAPITransformOrigin.cpp to the BUILD.gn file.
- Adds api_class flag to CSSProperties.in, which indicates that
  CSSPropertyAPITransformOrigin.h is generated.
- Moves the parsing logic for page from CSSPropertyParser.cpp to
  CSSPropertyAPITransformOrigin.cpp, which implements CSSPropertyAPI.h.
