Declare most TS 18661-1 interfaces for C2X.
C2X adds the interfaces from TS 18661-1, and all except a handful in Annex F are unconditionally visible in C2X rather than only visible when __STDC_WANT_IEC_60559_BFP_EXT__ is defined. This patch updates glibc headers accordingly: most uses of __GLIBC_USE (IEC_60559_BFP_EXT) are changed to a new __GLIBC_USE (IEC_60559_BFP_EXT_C2X). (Regarding totalorder and totalordermag, the type-generic macros in tgmath.h will go away when the functions are changed to take pointer arguments.) * bits/libc-header-start.h (__GLIBC_USE_IEC_60559_BFP_EXT): Update comment.
