til_settings: add til_setting_spec_t.as_label
Currently settings instances get labels from three sources:
1. explicitly labeled by a root-level til_settings_new() call,
like main.c::til_settings_new(NULL, "video", args->video);
2. implicitly labeled in a spec.as_nested_settings w/spec.key
3. positionally labeled in a spec.as_nested_settings w/o spec.key
But when constructing setting/desc paths, using strictly these
settings instance labels as the "directory name path component"
equivalent, leaves something to be desired.
Take this hypothetical module setting path for example:
/module/layers/[0]/viscosity
Strictly using settings instance labels as-is, the above is what
you'd get for the drizzle::viscosity setting in something like:
--module=compose,layers=drizzle
Which is really awkward. What's really desired is more like:
/module/compose/layers/[0]/drizzle/viscosity
Now one way to achieve that is to just create more settings
instances to hold these module names as labels and things would
Just Work more or less.
But that would be rather annoying and heavyweight, when what's
_really_ wanted is a way to turn the first entry's value of a
given setting instance into a sort of synthetic directory
component in the path.
So that's what this commit does. When a spec has .as_label
specified, it's saying that path construction should treat this
setting's value as if it were a label on a settings instance.
But it's special cased to only apply to descs hanging off the
first entry of a settings instance, as that's the only scenario
we're making use of, and it avoids having to do crazy things like
search all the entries for specs w/.as_label set.
It feels a bit janky but it does achieve what's needed with
little pain/churn.
