Drop support for anything below GHC 8.0.0, base 4.9.0.0, Cabal 1.24.0.0

[zlonast]

We don't have any testing for such old versions of ghc. Since this code isn't used, I assume it doesn't work, but it's difficult to confirm otherwise.

We just dropped everything below (ghc 8.0.0, base 4.9.0.0, cabal 1.24.0.0)

Template Α: This PR modifies behaviour or interface

Include the following checklist in your PR:

• Patches conform to the coding conventions.
• Any changes that could be relevant to users have been recorded in the changelog.
  • Is the change significant? If so, remember to add significance: significant in the changelog file.
• The documentation has been updated, if necessary.
• Manual QA notes have been included.
• Tests have been added. (Ask for help if you don’t know how to write them! Ask for an exemption if tests are too complex for too little coverage!)

Should we drop compilers below 8.6? Or 8.8?

This does modify behaviour, does it not?

[zlonast]

@ffaf1 It seems to me that if I can't compile the code with an old compiler, then this doesn't count as a change in behavior.

Makes sense!

I seem there are still review comments to be addressed so it may need some more work in general I love the idea and removing code is good. Thank you!

@zlonast could you please rebase?
