QtCore: fix the number precision in QJsonDocument.toJson()
In JSON, any number is stored in double. We need to make sure we
keep the maximum possible number precision for integer number. In
IEEE 754 double format, the significand precision is 53 bits(52
explicityly stored).
Autotest is included. qint64 and double work fine.
Task-number: QTBUG-28467
