[ci] Add 32bit 5.2.0 job

[ejgallego]

Caveats:

• The OCaml switch in this case byte-only, so things are slow, as jsoo itself won't have a native mode

• JS ppx libs 0.17 don't really support 32bit builds, this will likely become a problem in the future (if not now actually, for example ppx_inline_test.0.17.0 fails to build)

• jsCoq/coq-lsp works in this setup, which is IMO a great "data point" as to whether this setup is OK

p.s: Coq stops working in 5.2.0 if I pass --enable=effects tho, the error is Reason: Uncaught RangeError: Maximum call stack size exceeded, is that worth reporting?

[ejgallego]

Indeed, even if I did check git grep ppx_inline_test in JSOO sources, the package got pulled transitively.

So we either:

• drop this PR
• fix time_now.0.17.0 to build in 32bit (which may not be possible due to upstream policy)
• softer testing reqs for 5.2.0 + 32 bits

Any other idea?

No need to run the tests. Just build/install like we do for older ocaml version

@hhugo should we still do dune build @all --profile using-effects in the 5.2.0+32bit job?

As of now the @runtest part fails indeed.

Should should be able to use contains( matrix.ocaml-compiler, "ocaml-option-32bit")

Yes, we could. You could change the ci to respect skip test when skip-effect is false
