til_settings: add til_settings_get_count()

Getter for accessing til_settings_t.num

With recursive settings modules will start using settings
instances to represent things like lists of module names.
(modules/compose::layers for instance)

For those cases they'll want to know the number of settings in
the instance before iterating across getting their values
positionally.
