Reverting macro change of 'constexpr_*', removing the '_func' addition (shorter and correct).

Reverting macro change of 'constexpr_*' 112528c73f09b262bd53f817f9d9ff9343af0ee9, removing the '_func' addition.

This is not also back to the shorter version, but also correct as it reads since C++17:

"A `constexpr` specifier used in a function or static member variable (since C++17) declaration implies `inline`."

Hence it includes static member variables, not only covering functions.

Enhanced the API doc.
