* Resolves any type of link field or Prismic page to a set of link attributes.
* The attributes are designed to be passed to link HTML elements, like `<a>`.

* If a resolved URL is external (i.e. starts with a protocol like `https://`),
* `rel` is returned as `"noreferrer"`.

* @typeParam LinkResolverFunctionReturnType - link resolver function return
*   type
* @typeParam Field - Link field or Prismic page to resolve to link attributes
*
* @param linkFieldOrDocument - Any kind of link field or a page to resolve
* @param config - Configuration that determines the output of `asLinkAttrs()`
*
* @returns Resolved set of link attributes or, if the provided link field or
*   page is empty, and empty object
