feat(tvix): Add scripts for local nix daemon testing r/1735

These are the scripts I use to test the nix daemon interaction with a
non-/nix store directory during development, copied almost verbatim from
my cmake build directory. As such, there's likely a *lot* of cleanup and
deduplication to be done here, but I'm committing these as is in the
hope that others can benefit from them somehow.
