[functions] Support default values for parameters

If one or more trailing arguments are omitted, they can now gain
a default value instead.

Note that it's allowed (parse-time) to specify a parameter without
a default following one *with* a default. This is a bit weird,
so I've opened Issue 389974127 to see if we should change this.
