Replace hook_page_build() with working approach to add redirect from 404 page

The issue is about finding a suitable replacement for this feature, not just removing the code. It served a purpose, there's little to gain from just removing it.

I changed my opinion on this, also due to 📌 Replace hook_page_build() with working approach to add redirect from 404 page Needs work . Doesn't look like people are that interested in it, so lets remove it.

It does need a rebase though and should be converted to a MR.
