This reverts commit 85bc4ef6.

Reason for revert: The tag 'e' conflicts with a blink serialization tag: kFileIndexTag.

Original change's description:
> Serialize native errors
> 
> Make native errors serializable.
> 
> The implementation is mostly straightforward, but there is one
> exception: the stack property. Although the property is not specified,
> the spec for error cloning asks us to preserve the property if
> possible. This implementation serializes the property only when it is
> a string, and otherwise ignores it.
> 
> Spec: https://github.com/whatwg/html/pull/4665
> Intent-to-Ship: <TBD>
