Multiple mingw architectures resolved with 0install #6843
Description
Ever since setup-ocaml changed to use 0install by default, mingw packages are resolved with i686 and x86_64 variants, whereas previously only the x86_64 variants were installed.
This is haxe's opam file, which includes conf-zlib and conf-libpcre2-8:
https://github.com/HaxeFoundation/haxe/blob/21ae9743bbe7c94a317a6b6f9409ff4218723335/haxe.opam#L31-L32
`builtin-0install` package list resolves `conf-mingw-w64-pcre2-i686` alongside `conf-mingw-w64-pcre2-x86_64`, etc.

The following system packages will first need to be installed:
mingw64-x86_64-pcre2 mingw64-x86_64-zlib pkgconf
Here are the dependency conditions for conf-zlib:

and conf-libpcre2-8:

Seems similar to #6674.
