  stdckdint-h: Don't generate header if it is not needed.
  
  Suggested by Paul Eggert in:
  <https://lists.gnu.org/archive/html/bug-gnulib/2025-05/msg00216.html>.
  
  * m4/stdckdint_h.m4: New file.
  * modules/stdckdint-h (Files): Add m4/stdckdint_h.m4.
  (configure.ac): Remove checks and just invoke gl_STDCKDINT_H.
  (Makefile.am): Replace variables set by ./configure.
  * lib/stdckdint.in.h: Include the compilers header if it exists.  Add
  comment mentioning expected future standardization in C++26.
  (ckd_add, ckd_sub, ckd_mul): Only define if the compilers definitions do
  not work.
