core: use GHC 9.6.2 (#2641)

* Make it compiler with 9.6

Can be built with:

cabal build all -j --allow-newer=base --allow-newer=ghc-prim --allow-newer=template-haskell --allow-newer=bytestring --allow-newer=memory --allow-newer=cryptonite

Using ghc 9.6

It mostly runs afoul of https://github.com/ghc-proposals/ghc-proposals/blob/master/proposals/0366-no-ambiguous-field-access.rst

* update simplexmq, sha256map.nix

* update compiler

* update simplexmq, direct-sqlcipher

* remove missing files from .cabal
