feat(nix-compat/nix_http): init parse_nar[info]_str r/8547

This moves the URL component parsing code we had in nar-bridge to
nix-compat.

We change the function signature to return an Option, not a
Result<_, StatusCode>.

This allows returning more appropriate error codes, as we can
ok_or(…) at the callsite, which we now do: on an upload to an
invalid path, we now return "unauthorized", while on a GET/HEAD, we
return "not found".

This also adds support to parse compression suffixes. While not
supported in nar-bridge, other users of nix-compat might very well want
to parse these paths.

Also fix the error message when parsing NAR urls, it mentioned 32, not
52, which is a copypasta error from the narinfo URL parsing code.
