nix-everything: Remove libs, add dev and devdoc package outputs

[roberth]

Reshuffle everything.nix so that it's still tested, has multiple package outputs, but is not bloated.

Motivation

Bring out back to its old size

• Huge closure size increase in the default Nix package #11864

$ nix path-info -Sh nix/2.24.10#default.out
copying '/nix/store/n41ic7p1zsjir4ra9g7khrdlgyb4jgvl-source' to the store/nix/store/hdy82qidsybc3fg561pqfwagv44vschb-nix-2.24.10          93.8 MiB

$ nix path-info -Sh result/
/nix/store/q3rv37qwyskxs9g4gpa7pfwl7gx6mj80-nix-2.26.0pre20241112_dirty   92.9 MiB

Context

The new package output attributes are somewhat experimental, and provided for compatibility most of all.

We'll see how well this goes before the changes proposed in #6507

Priorities and Process

Add 👍 to pull requests you find important.

The Nix maintainer team uses a GitHub project board to schedule and track reviews.

LGTM. In a perfect world, buildEnv would have multiple output support so it could do this for us...

Looks like this is still missing Library/LaunchDaemons/org.nixos.nix-daemon.plist as per #11862

$ diff -u <(tree -l $(nix build --no-link nix/2.24.10 --json | jq -r '.[0].outputs.out')) <(tree -l $(nix build --no-link nix/unbloat-nix-everything --json | jq -r '.[0].outputs.out'))
