Assume wchar_t |

The vasnprintf module still has #if HAVE_WCHAR_T conditionals. But we haven't
seen a platform without wchar_t maybe 20 years. wchar_t was introduced
a couple of years before C99, and X11 relies on it extensively.
So, it's time to simplify things and assume that wchar_t exists.

Assume wchar_t.
* lib/stddef.in.h (wchar_t): Remove fallback definition.
* m4/stddef_h.m4 (gl_STDDEF_H): Don't require gt_TYPE_WCHAR_T. Assume
gt_cv_c_wchar_t is 'yes'.
(gl_STDDEF_H_DEFAULTS): Don't initialize HAVE_WCHAR_T.
* modules/stddef (Files): Remove m4/wchar_t.m4.
(Makefile.am): Don't substitute HAVE_WCHAR_T.
* doc/posix-headers/stddef.texi: Don't mention the problem of a missing
wchar_t.
