Original change's description:
> [ChromeDriver] Remove unused shadow DOM object cache
> 
> ChromeDriver uses object caches for use while calling JavaScript
> functions. The data structure was designed to allow a separate cache for
> each shadow DOM, but that feature was never used, and objects in shadow
> DOMs have always been stored in the main page cache. This CL removes
> unused code, and resolves differences between test expectancies and
> actual code behavior. It prepares for future changes to make the object
> cache standard compliant.
