  win32: Simplify gmtime_r detection not depends on if _POSIX_C_SOURCE are 
defined on msys2/mingw

We remove the CONFIG_LOCALTIME_R detection option in configure, and move the 
check
existence of gmtime_r from configure into C header and source directly by using 
macro
`_POSIX_THREAD_SAFE_FUNCTIONS`.
Before this patch, the configure script are always assume the compiler doesn't 
define
_POSIX_C_SOURCE macro at all, but that's not true, because thirdparty library 
such
as ncursesw may define -D_POSIX_C_SOURCE in it's pkg-config file. And that C 
Flags will
added -D_POSIX_C_SOURCE into each QEMU_CFLAGS. And that's causing the following 
compiling error:

After this patch, whenever ncursesw or other thirdparty libraries tried to 
define or not
define  _POSIX_C_SOURCE, the source will building properly. Because now, we 
don't make any
assumption if _POSIX_C_SOURCE are defined. We solely relied on if the macro 
`_POSIX_THREAD_SAFE_FUNCTIONS`
are defined in msys2/mingw header.

The _POSIX_THREAD_SAFE_FUNCTIONS are defined in mingw header like this:

```
#if defined(_POSIX_C_SOURCE) && !defined(_POSIX_THREAD_SAFE_FUNCTIONS)
#define _POSIX_THREAD_SAFE_FUNCTIONS 200112L
#endif

#ifdef _POSIX_THREAD_SAFE_FUNCTIONS
__forceinline struct tm *__CRTDECL localtime_r(const time_t *_Time, struct tm 
*_Tm) {
  return localtime_s(_Tm, _Time) ? NULL : _Tm;
}
__forceinline struct tm *__CRTDECL gmtime_r(const time_t *_Time, struct tm 
*_Tm) {
  return gmtime_s(_Tm, _Time) ? NULL : _Tm;
}
__forceinline char *__CRTDECL ctime_r(const time_t *_Time, char *_Str) {
  return ctime_s(_Str, 0x7fffffff, _Time) ? NULL : _Str;
}
__forceinline char *__CRTDECL asctime_r(const struct tm *_Tm, char * _Str) {
  return asctime_s(_Str, 0x7fffffff, _Tm) ? NULL : _Str;
}
#endif
```

./chardev/baum.c expects the default window_id value to be -1, and not 0

This fixes getting Braille output with the curses and gtk frontends.
