Prior patches in 54dc5314e8
and 6db6190002 fixed the default
system double for i686 and ppc/ppc64. This also patch also covers
32 bit arm and mips. ARM cpu names are taken from host_machine.cpu()
for a lack of a better option, but host_machine.cpu_family() is
preferred, since that is supposed to be somewhat standard for cross
files. Endianness is handled correctly by looking at host_machine.endian().
This also updates the documentation to be up to date to how system cpu
is translated from the host_machine specification.

I've missed this while reviewing 6db6190002.
I only built big endian ppc64, so that didn't occur to me.
From meson manual:
> Those porting from autotools should note that Meson does not add
> endianness to the name of the cpu_family. For example, autotools will
> call little endian PPC64 "ppc64le", Meson will not, you must also check

This code should handle that correctly.

This adds a meson.format file that mostly mirrors the projects
meson style and a pre-commit hook to enforce this style.
Some low-diff files are formatted.
The short answer for why we need to do this is so we can consistently do
`#include "nix/..."`. Without this change, there are ways to still make
that work, but they are hacky, and they have downsides such as making it
harder to make sure headers from the wrong Nix library (e..g.
`libnixexpr` headers in `libnixutil`) aren't being used.
The C API alraedy used `nix_api_*`, so its headers are *not* put in
subdirectories accordingly.
Progress on #7876
We resisted doing this for a while because it would be annoying to not
have the header source file pairs close by / easy to change file
path/name from one to the other. But I am ameliorating that with
symlinks in the next commit.
Fix a footgun. In my case, I had a couple of build ("output")
directories sitting around.
rm -rf build-*
Was confused for a bit why a meson.build file was missing.
Probably also helps with autocompletion.
I tried meson-build-support first, but I had to add something like
a nix- prefix, in order to make meson happy. They've reserved the
meson- prefix.
