[WIP] Update to GHC 9.0.2/Stackage LTS-19.0
And so... the ~~hunt~~ fun begins again!

### Core packages to bump

- [x] ghc
- [ ] ghc-bin
    - [x] x86_64-musl [Link](https://download1640.mediafire.com/02oxtdmod6tg/2g0umndrffyechx/ghc-9.0.2-x86_64-void-linux-musl.tar.xz) **Not uploaded yet**
    cc. @q66 for the following
    - [ ] ppc64le
    - [ ] ppc64le-musl
    - [x] aarch64 [Link](https://ftrv.se/_/void/ghc-9.0.2/ghc-9.0.2-aarch64-void-linux.tar.xz) **Not uploaded yet**
    - [x] aarch64-musl [Link](https://ftrv.se/_/void/ghc-9.0.2/ghc-9.0.2-aarch64-void-linux-musl.tar.xz) **Not uploaded yet**
- [x] cabal-install
- [x] stack

#### Rebuild literally every single haskell package we have and see if anything's broken

Most of these are already done, things should probably go smoothly as 9.0.x does not contain any big breaking changes.

- [x] git-mediate
- [x] kmonad
- [x] cgrep
- [x] debug-me
- [x] hlint
- [x] hoogle
- [x] darcs
- [x] shellcheck
- [x] git-annex
- [x] hledger
- [x] pandoc (contains a fix for `pandoc-crossref` on musl \o/)
- [x] xmobar
- [x] haskell-language-server

### Other things to do 

- [x] Either incorporate https://github.com/void-linux/void-packages/pull/36193 into this PR or merge it first and then rebuild GHC for aarch64 and aarch64-musl; cc. @ftrvxmtrx
