Move DOM attributes to prototype chains.

Summary

Blink has placed DOM attributes on instances instead of prototypes. However, the Web IDL spec requires that DOM attributes must be placed on prototype chains (except for a few exceptions such as static attributes and [Unforgeable].) We move DOM attributes on instances to prototype chains following the spec.
