Subject: [PATCH] Privacy: Add `rel="privacy-policy"` to the Privacy Policy
 link.

This changeset adds a `rel="privacy-policy"` attribute to user-facing links to the Privacy Policy of the website, when a privacy policy page is set and available. While this `rel` value is still a RFC of the Link Types HTML specification, this changeset helps to make Privacy Policy link more discoverable for user agents and HTML parsers.

Fixes #56345.
