Add `universum-prelude`

[Martoon-00]

Description

Add an easy way to implicitly import Universum in other projects.

I'm yet about to test it. Unfortunately, the maintainer of base-noprelude is away for some time already, and base-noprelude is now too outdated to be used in any of our projects, see https://github.com/haskell-hvr/base-noprelude/issues/11.

I didn't update cI workflows, since stack build already covers the new module, and the new package is too small to test it with cabal too.

• Tests

  • [x] If I added new functionality, I added tests covering it.
  • [x] If I fixed a bug, I added a regression test to prevent the bug from silently reappearing again.

• Documentation

  I checked whether I should update the docs and did so if necessary:

  • [x] README
  • [x] Haddock

• Record your changes

  • [x] I added an entry to the changelog if my changes are visible to the users and
  • [x] provided a migration guide for breaking changes if possible

Stylistic guide (mandatory)

• [x] My commit history is clean (only contains changes relating to my issue/pull request and no reverted-my-earlier-commit changes) and commit messages start with identifiers of related issues in square brackets.

  Example: [#42] Short commit description

  If necessary both of these can be achieved even after the commits have been made/pushed using rebase and squash.

I think this can be merged, right?

I failed to test the new universum-prelude (I tried in xrefcheck) because base-noprelude was not updated for a while and there is no version that would match the LTS we use. And looks like base-noprelude's maintainer is yet gone, so we are in a quite unpleasant situation for now :crying_cat_face:
