Instead of hardcoding all nss modules that are added into nsswitch,
there are now options exposed.
This allows users to add own nss modules (I had this issue with
winbindd, for example).
Also, nss modules could be moved to their NixOS modules which would
make the nsswitch module slimmer.
As the lists are now handled by the modules system, we can use mkOrder
to ensure a proper order as well as mkForce to override one specific
database type instead of the entire file.
Commit 987aac7 and issue #18183 were intended to fix support for other
things, but in the process, changed mdns_minimal to use the wrong return
setting, resulting in permanent failures in early boot, affecting things
like issue #30459.

In order for DynamicUser = true to work in services, we need the
nss-systemd module to be able to resolve the user and group names
generated dynamically.

Closes #21150
Using pkgs.lib on the spine of module evaluation is problematic
because the pkgs argument depends on the result of module
evaluation. To prevent an infinite recursion, pkgs and some of the
modules are evaluated twice, which is inefficient. Using ‘with lib’
prevents this problem.
