til: add til_module_setup_finalize() helper

Preparatory commit for til_module_create_context() requiring
setups even when there's no til_module_t.setup() method.

This helper will produce the minimal til_setup_t in such cases,
or hand off the task to til_module_t.setup() when present.

Note the need for passing res_setting and res_desc to
til_module_t.setup() despite not being a settings-construction
scenario.  This is because of how modules using nested settings
tend to use res_setting for storing the current setting in
accessing the nested instance, which must still occur even when
just baking the complete setup.

It's expected that any composite/meta modules utilizing other
modules will use this helper to produce the baked setups, instead
of the ad-hoc direct calling of til_module_t.setup() they do
presently.
