Move object literal checking into checker classes

by two subclasses to ObjectLiteralCheckerBase called ObjectLiteralChecker
and ClassLiteralChecker.

The object literal checker now only checks for duplicate __proto__ fields in

fields named constructor as well as static properties named prototype.
