Subject: refactor(xan): Simplify build infrastructure

Simplify the build infrastructure for creating shells etc. for xanthous,
including relying more heavily on stuff exposed in Depot anyway, using
shellFor in the shell.nix, and using the haskell.nix branch of all-hies
for a significantly simpler build. At some point the all-hies stuff will
likely want to be promoted up to //third_party, but for now it's
experimental enough that I don't want to bother other people with it.
