Feeds: Introduce the `get_self_link()` function.

Corresponds to the `self_link()` template function.

This matches other feed template functions, using one function to get the value, and a different function to echo it.

Props jojotjebaby, mobeen-abdullah, donmhico, audrasjb, dshanske.
Fixes #44838.
