After final improvements to the official formatter implementation,
this commit now performs the first treewide reformat of Nix files using it.
This is part of the implementation of RFC 166.
Only "inactive" files are reformatted, meaning only files that
aren't being touched by any PR with activity in the past 2 months.
This is to avoid conflicts for PRs that might soon be merged.
Later we can do a full treewide reformat to get the rest,
which should not cause as many conflicts.
A CI check has already been running for some time to ensure that new and
already-formatted files are formatted, so the files being reformatted here
should also stay formatted.

This change switches the xar package from unmaintained fork of the
original project to the Apple Open Source tarball. See also
https://repology.org/project/xar/versions
Since the package is essentially rewritten from scratch, we take an
opportunity and move it to pkgs/by-name/xa/xar (formatted with nixfmt).
We also remove Windows from the supported platforms because even before
this change pkgsCross.mingwW64.xar failed with
xar> configure: error: can not detect the size of your system's uid_t type
