Fix compiler warnings in init_dump_ascii_wstr() (GH-22150)
Fix GCC 9.3 (using -O3) warnings on x86:
initconfig.c: In function ‘init_dump_ascii_wstr’:
initconfig.c:2679:34: warning: format ‘%lc’ expects argument of type
‘wint_t’, but argument 2 has type ‘wchar_t’ {aka ‘long int’}
2679 | PySys_WriteStderr("%lc", ch);
initconfig.c:2682:38: warning: format ‘%x’ expects argument of type
‘unsigned int’, but argument 2 has type ‘wchar_t’ {aka ‘long int’}
2682 | PySys_WriteStderr("\\x%02x", ch);
initconfig.c:2686:38: warning: format ‘%x’ expects argument of type
‘unsigned int’, but argument 2 has type ‘wchar_t’ {aka ‘long int’}
2686 | PySys_WriteStderr("\\U%08x", ch);
initconfig.c:2690:38: warning: format ‘%x’ expects argument of type
‘unsigned int’, but argument 2 has type ‘wchar_t’ {aka ‘long int’}
2690 | PySys_WriteStderr("\\u%04x", ch);
