stdio: ISO C 23: Define _PRINTF_NAN_LEN_MAX.
* lib/stdio.in.h (_PRINTF_NAN_LEN_MAX): New macro.
* m4/stdio_h.m4 (gl_STDIO_H): Invoke gl_MUSL_LIBC.
* modules/stdio (Files): Add m4/musl.m4.
* tests/test-stdio.c: Check that _PRINTF_NAN_LEN_MAX is defined.
Include nan.h, macros.h.
(main): Check the value of _PRINTF_NAN_LEN_MAX.
* modules/stdio-tests (Files): Add tests/nan.h, tests/macros.h,
m4/exponentd.m4.
(configure.ac): Invoke gl_DOUBLE_EXPONENT_LOCATION.
