0cb36296 - [libc++][format] Disables the FTM on older MacOS versions. (#126547)

[libc++][format] Disables the FTM on older MacOS versions. (#126547) On older MacOS versions where `std::to_chars` for floating-point types is not available the format library can't be used. Due to some issue with the availability macro used to disable format on MacOS the issue triggers regardless of the type being formatted. The print library has the same issue. Fixes: #125353
