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.
Doing this makes catching non-obvious bugs easier. GHA CI workload is
already a concern and there isn't much benefit in running the tests with
and without sanitizers at the same time, so UBSAN is enabled for default
checks.
This change doesn't affect production builds in any way, but is rather a
step in the direction of improving automated testing during development.
Relates to #10969.
We're not replacing `Path` in exposed definitions in many cases, but
just adding alternatives. This will allow us to "top down" change `Path`
to `std::fileysystem::path`, and then we can remove the `Path`-using
utilities which will become unused.
Also add some test files which we forgot to include in the libutil unit
tests `meson.build`.

This ended up motivating a good deal of other infra improvements in
order to get Windows right:
- `OsString` to complement `std::filesystem::path`
- env var code for working with the underlying `OsString`s
- Rename `PATHNG_LITERAL` to `OS_STR`
- `NativePathTrait` renamed to `OsPathTrait`, given a character template
parameter until #9205 is complete.
Split `tests.cc` matching split of `util.{cc,hh}` last year.

The test split matches PR #8920, so the utility files and tests files
are once again to 1-1. The string changes continues what was started in
PR #11093.
When the separator is empty, no difference is observable.
Note that concatStringsSep has centralized definitions. This adds the
required definitions. Alternatively, `strings-inline.hh` could be
included at call sites.
