All the new <float.h> macros should be under a
__STDC_WANT_IEC_60559_TYPES_EXT__ conditional like the _FloatN / _FloatNx
ones are (together of course with a conditional that DFP is supported),
since this is an Annex H feature.

This one would require all three conditionals
(__STDC_WANT_IEC_60559_TYPES_EXT__, DFP supported, C23) as it wasn't in TS
18661-3.
