Currently the data tables can't be used in a constexpr function. This is
required to implement P2291R3 "Add Constexpr Modifiers to Functions
to_chars and from_chars for Integral Types in <charconv> Header"

Since inline constexpr variables are supported since C++17 use this them
starting from C++17. Before use the old tables and a reference helper
variable.
