Use let-in aware prod_applist_assum in dtauto and firstorder.
Fixes #6490. `prod_applist_assum` is copied from `kernel/term.ml` to `engine/termops.ml`, and adjusted to work with econstr. This change uncovered a bug in `Hipattern.match_with_nodep_ind`, where `has_nodep_prod_after` counts both products and let-ins, but was only being passed `mib.mind_nparams`, which does not count let-ins. Replaced with (Context.Rel.length mib.mind_params_ctxt).
