lib.attrsets.attrsToList: add function

For transforming back between lists and attrsets, it makes sense to have
a quasi-inverse of `builtins.listToAttrs` available as a library
function.

Like `unlines` from Haskell.
The aim is to replace the `concatStringsSep "\n"` pattern for generated

nixos/doc: render option values using lib.generators.toPretty
...
Render un`_type`d defaults and examples as `literalExpression`s using
`lib.generators.toPretty` so that consumers don't have to reinvent Nix
pretty-printing. `renderOptionValue` is kept internal for now intentionally.
Make `toPretty` print floats as valid Nix values (without a tilde).
Get rid of the now-obsolete `substSpecial` function.
Move towards disallowing evaluation of packages in the manual by
raising a warning on `pkgs.foo.{outPath,drvPath}`; later, this should
throw an error. Instead, module authors should use `literalExpression`
and `mkPackageOption`.

lib/generators.toPretty: don't evaluate derivations
...
With the goal of making `toPretty` suitable for rendering option
values, render derivations as `<derivation foo-1.0>` instead of
`<derivation /nix/store/…-foo-1.0.drv>`.
This is to avoid causing sudden evaluation errors for out-of-tree
projects that have options with `default = pkgs.someUnfreePackage;` and
no `defaultText`.
