LibJS: Add non-BigInt overload of round_number_to_increment()

Browse source 
Unlike the spec we chose BigInt for the input and output types here as
it was being used with ℝ(ns), ns being of type BigInt, in one place and
a conversion to double would not be safe.
Since in many places we'll have double input values, let's add a double
overload of this function to avoid awkward conversions and expensive
allocations.
