Refactor PRINT_FPHEX_LONG_DOUBLE into a reusable macro
This patch refactors the macro PRINT_FPHEX_LONG_DOUBLE from the file sysdeps/ieee754/ldbl-128/printf_fphex.c into a function-like macro to enable its use for both long double and _Float128, when they are ABI-distinct. * sysdeps/ieee754/ldbl-128/printf_fphex.c: Include ldbl-128/printf_fphex_macros.h for the definition of PRINT_FPHEX. (PRINT_FPHEX_LONG_DOUBLE): Define based on PRINT_FPHEX. * sysdeps/ieee754/ldbl-128/printf_fphex_macros.h (PRINT_FPHEX): New function-like macro that can be used for long double, as well as for _Float128
