migrate from `useNA` to `na.rm` arguments in teal module arguments

It is more general and not just applicable for factor tabulation... I think long term we should change the teal module argument. Then it will also be consistent with `tern`.

Start by locating teal module arguments that use `useNA` and compare their interfaces with `tern`, as requested in the issue. Determine the complete set of modules affected and define the migration scope before changing arguments; done means the relevant teal modules consistently use `na.rm`.
