Work around a Clang <15 bug by switching to ARRAY_SIZE() (with the
added benefit of explicitly checking for char array arguments) in
memtostr*/strtomem*().

 v2:
  - change __must_be_byte_array to __must_be_byte_array() (david)
  - add missed Suggested-by (kent)
  - clarify move log (miguel)
  - clarify cover letter Clang version (andy)
 v1: https://lore.kernel.org/lkml/20250206175216.work.225-kees@kernel.org/
