refactor: use fold expressions instead of recursive calls in SerializeMany()

Browse source 
Instead of recursively calling `SerializeMany` and peeling off one
argument at a time, use a fold expression. This simplifies the code,
makes it most likely faster because it reduces the number of function
calls, and compiles faster because there are fewer template
instantiations.
