Merge branch 'eagles-project/mjs271/mam4xx/ff-submodule' (PR #6867)

This PR fixes the MAM4xx interface for wet scavenging--namely, addressing failing tests and an associated non-determinism issue.

The issues existed primarily on the MAM4xx side of things, so this PR is mostly a fast-forward of the MAM4xx submodule. However, minor edits to the EAMxx interface code were required in order to properly call mam4::wetdep::aero_model_wetdep().
