DefaultEquality<E> class Null safety

Equality of objects that compares only the natural equality of the objects.

This equality uses the objects' own Object.== and Object.hashCode for the equality.

Note that equals and hash take Objects rather than Es. This allows E to be inferred as Null in const contexts where E wouldn't be a compile-time constant, while still allowing the class to be used at runtime.
