[issue9642] #ifdef and mbcs: don't check for defined(HAVE_USABLE_WCHAR_T)

[STINNER Victor]

STINNER Victor <victor.stinner at haypocalc.com> added the comment:

Version 3 of the patch:
 - fix initialization of the filesystem encoding if HAVE_MBCS is not set
 - Python fails on the filesystem encoding if it is unable to get the filesystem encoding instead of using UTF-8
 - reorganize the definition of time_clock() function
 - cleanup how TZNAME_ENCODING is defined in timemodule.c

The change on initfsencoding() should be defined in a separated commit.
