include/stdckdint.h: make the header compatible with C++

by removing the cast to _Bool. The _Bool type is not defined for C++,
and the specification from the gcc info doc states that the return
type of the __builtin_{add,sub,mul}_overflow() is bool already.

This is done instead of including stdbool.h to avoid namespace
pollution, since defining bool from stdckdint.h simingly is not
sanctioned by ISO/IEC 9899:2024.

include: Implement N2867.

This adds macros for checked addition, subtraction, and multiplication with semantics similar to the builtins gcc and clang have had for years.
