[WP] Add Token Filter to core

Description of the need

This is a formal request to have Token Filter added to core as a text format filter.

Both Drupal and Wordpress work on a token system in the backend, however Drupal nor Backdrop make it easy to expose the tokens to the front-end out of the box. Wordpress (from my understanding) does expose their tokens to the frontend without any additional plugins to accomplish it.

Proposed solution

Token Filter is one of my go-to modules that needs installed, just to be able to use the date token for a website copyright. It is rare that I use tokens in other places on sites (depending on the site), however the fact that none of the tokens are exposed to the frontend without a contrib to accomplish it, makes it difficult for new users to know that tokens exist.

Alternatives that have been considered

The only current alternative is to use contrib.

Another alternative is to expose a small, pre-defined set of tokens instead of all tokens. Contrib could be used to expose any additional tokens that aren't exposed by core.

Is there a Drupal or Backdrop contributed module that accomplishes this?

Additional information

I'm not big on bloating core, however this is one aspect of Drupal (and now Backdrop) that I have always pondered: "Why do tokens exist in core if core doesn't do anything to easily expose them?" I'm all for tokens being a part of core, but I'm also all for the ability to use the tokens through core.
