	Sometimes nested modules are optional, in those cases I've usually been using the "none" module name to indicate this and the ad-hoc setup stuff can easily bypass module setup on that. This commit is a step towards having a "none" builtin that provides a til_module_t.setup() which succeeds but only produces a NULL res_setup when asked to finalize. So if callers just handle a successful finalize case that writes NULL at res_setup equivalent to "disabled", this all Just Works. Currently that's not an expected thing, but future commits will bring everything else on the same page. For callers who want to require the module and not offer "none", they can just put "none" in the explicit exclusions list passed to til_module_setup_full().
2023-08-05	til: make builtins first-class modules w/new flag	Vito Caputo
	Also move builtins to a separate listing while at it For now this results in the builtins showing up in the modules list alongside the actual rendering modules. Future work must refine this UX, maybe by adding some metadata to the spec.values for categorizing/prioritizing what's shown always vs. what's present but hidden without asking to be shown hidden stuff or whatever. Just consolidating some junk and working towards every nested module setup going through the same machinery, and always being able to access the builtins.
