Fix MS-Win system locale code to return QString for numeric tokens

QSystemLocale::query() is specified to return a QString (wrapped in a
QVariant) for the various tokens used in formatting numbers (zero
digit, signs, separators) but the MS-Win back-end was returning QChar
(wrapped as QVariant) instead, using the first UCS-2 code-point of the
string (even if this was the first of a surrogate pair). The same
error shall be perpetrated by its caller, but we can at least DTRT in
the back-end, ready for the coming fix (in Qt 6) to its caller.

In the process, eliminate some local variables that shadowed a member
variable and adapt number-conversion to cope with surrogate-pair
digits. Optimised the latter for the case where zero is "0".
