crt: crtdll and msvcrt10: Add support for C95 getwc(), getwchar(), putwc(), putwchar() functions

Browse Source 
All CRT libraries provide fgetwc, _fgetwchar, fputwc and _fputwchar
symbols. They are aliases of the C95 functions getwc, getwchar, putwc and
putwchar.

CRT libraries crtdll.dll and msvcrt10.dll do not export these functions
under C95 names. So define aliases in def files for C95+ compatibility.
