new modules setpayload, setpayloadf, setpayloadl

[Bruno Haible]

ISO C 23 specifies in the (optional, but normative) Annex F functions
for creating NaNs with payload.

glibc has these functions already since 2017. But portable programs
cannot use them, if Gnulib does not implement them as well.

Therefore, this set of patches implements them.
