(*
Check module inclusion M1 : MT1 @ m1 <= MT2 @ m2.
No prior constraint between m1 and m2 is given. In particular, it's possible that m1 >= m2. For example, if m1 = nonportable >= portable = m2 and MT2 = sig end, the inclusion check should pass. This finer treatment is necessary for ergonomics.
Another ergonomics is wrt closing over modules. If M1 is a Pmod_ident, all surrounding functions would naively close over M1. However, if M1 = nonportable and MT2 = sig end, surrounding functions shouldn't be forced to nonportable. To that end, the locks leading to M1 is not walked immediately upon look-up, but held and passed to inclusion check for finer treatment. This is the third constructor argument. This is similar to the ergonomics in Typecore.type_ident wrt projections out of modules.

Describes the modes of modules on both sides, passed to inclusion check.

val child_modes : string -> mmodes -> mmodes

Gives the modes suitable for the inclusion check of a child item, where there is no modality between the parent and the child. Takes the modes suitable for the parent item.

val child_modes_with_modalities : 
  string ->
  modalities:(Mode.Modality.t * Mode.Modality.t) ->
  mmodes ->
  (mmodes, Mode.Modality.error) Result.t

Gives the modes suitable for the inclusion check of a child item. Takes the modes suitable for the inclusion check of the parent item, and both hands' modalities between the parent and the child.

  Env.t ->
  ?crossing:Mode.Crossing.t ->
  item:Ocaml_typing.Mode.Hint.lock_item ->
  ?typ:Types.type_expr ->
  mmodes ->
  (unit, Mode.Value.error) Result.t

Claim the current item is included by the RHS and its mode checked.
