We offer full cgroup delegation to our sandbox now, required for running containers inside the sandbox. To run systemd-nspawn or containers managers inside the sandbox, there is a need for one extra ingredient now: control over your own cgroup subtree inside the sandbox. If, in addition, you need multiple UIDs, for e.g. rootless usecases, you need to run with the `uid-range` system feature. Therefore, when the daemon or Nix runs under the right condition, e.g. systemd-style delegation of the cgroup subtree while placing the nix-daemon in a supervisor sub-cgroup, we create a new sub-cgroup for each build based on the build UID and delegate that sub-cgroup to the builder's process. Additionally, `uid-range` always request the `cgroups` feature now, as `uid-range` builds would probably always benefit from having cgroups delegated, but the converse is not true. Inspired from https://github.com/NixOS/nix/pull/11412 with a different design that does not use function-local statics to derive the root cgroup.
