7d67db3919 shellFor: Refactor for consistency and cross 
This makes it work like work-on-multi from Reflex Platform. In
particular, rather than making `.env` from `shellFor`, we make `.env`
the primitive, and `shellFor` works by combining together the arguments
of all the packages to `generic-builder` and taking the `.env` of the
resulting mashup-package.

There are 2 benefits of this:

1. The dependency logic is deduplicated. generic builder just concatted
   lists, whereas all the envs until now would sieve apart haskell and
   system build inputs. Now, they both decide haskell vs system the same
   way: according to the argument list and without reflection.
   Consistency is good, especially because it mean that if the build
   works, the shell is more likely to work.

2. Cross is handled better. For native builds, because the
   `ghcWithPackages` calls would shadow, we through both the regular
   component (lib, exe, test, bench) haskell deps and Setup.hs haskell
   deps in the same `ghcWithPackages` call. But for cross builds we use
   `buildPackages.ghcWithPackages` to get the setup deps. This ensures
   everything works correctly.

Since [1], cabal2nix has been able to parse full platform triples. We
need this for when the system doesn't say enough info (e.g. android).

Add minimal docs for callHackage and friends 
Specifically haskellSrc2nix, callHackage, and callHackageDirect. Other
functions should probably also be documented, but it's at least a start.

62882d8cd2 haskellSrc2nix: disallow substitutes 
Fix #49818. See the bug for more details.

The work done by haskellSrc2nix is usually lightweight, but needs to
be done each time a cabal file change. This triggers unexpected
network activity for a cache query which results most of the time on a
cache miss.

By disabling substitutes we:

- avoid the, mostly useless, binary cache query
- avoid unexpected network failure when users change a cabal file and
  try to rebuild without connectivity.

bf687907d7 haskell lib: Make Cabal compiler names explicit 
Cabal2nix expects a --compiler flag that contains a Cabal Compiler description.
We used to use the compiler's derivation name for this, but this breaks when
cross-compiling due to the target suffix. Instead we add an explicit
haskellCompilerName attribute to Haskell compiler derivations.
