js-on-sx: built-in .length returns spec-defined values
String.fromCharCode.length, Math.max.length, Array.from.length
were returning 0 because their SX lambdas use &rest args with no
required params — but spec assigns each a specific length.
Added js-builtin-fn-length mapping JS name to spec length (12
entries). js-fn-length consults the table first and falls back to
counting real params.
