refactor(nix/buildLisp): prepare multi implementation support r/2767
Concept is roughly:

* receive extra argument `implementation` that refers to the name of an
  implementation or rather an attribute in an internal attribute set
  telling buildLisp how to do certain build steps.

* We assume an implementation can execute lisp files as scripts and that
  we can implement the following main tasks in lisp:

  - Building a library (`genCompileLisp`)

  - Building an executable (`genDumpLisp`)

  - Loading a library dynamically (`genLoadLisp`)

  Based on that we can implement:

  - Running a test suite (`genTestLisp`)

  - A REPL preloaded with a libraries and their dependencies (`lispWith`)

  Additional attributes for implementing these parts genericly  are
  added as needed (`faslExt` and `runScript`).

* `genCompileLisp` no longer prints a shell script which concatenates
  the individual FASLs. Instead it does the step previously done by the
  shell script itself. In essence `genCompileLisp` now writes a lisp
  script which compiles and installs the library to build.
  This will allow us extra freedom for different implementations, e. g.
  for ECL we'll want to build a object file archive additionally to fasl
  files in order to be able to link proper executables.

* `genLoadLisp` and `genTestLisp` are almost generic (the former just
  sometimes would need to use different file extensions), but we
  integrate them into the implementation “API” to facilitate minor
  tweaks we need to do like the `fasc` extension for ECL's native FASL
  files.
