llvmPackages_16: drop

- GCC 9, 10, 11, and 12 have been removed, as they have reached end‐of‐life upstream and are no longer supported.

- LLVM 12, 13, 14, and 15 have been removed, as they have reached end‐of‐life upstream and are no longer supported.

- LLVM 12, 13, 14, 15, and 16 have been removed, as they have reached end‐of‐life upstream and are no longer supported.

- GHCJS 8.10, exposed via `haskell.compiler.ghcjs` and `haskell.compiler.ghcjs810`, has been removed. Downstream users should migrate their projects to the new JavaScript backend of GHC proper which can be used via `pkgsCross.ghcjs` from Nixpkgs. Haskell packaging code, like `haskellPackages.mkDerivation`, `ghcWithPackages` and `hoogleWithPackages`, also no longer supports GHCJS.
