Remove usages of deprecated APIs from QDateTime

- Replaced the usages of:
  * QDateTime::toTime_t() -> QDateTime::toSecsSinceEpoch().
  * QDateTime::fromTime_t() -> QDateTime::fromSecsSinceEpoch().
  * QDate::shortDayName() -> QLocale::system().dayName().
  * QTime by QElapsedTimer, where the deprecated methods of QTime
    were used.

- Modified the tests for the deprecated methods to be enabled only
  when the corresponding methods are enabled: when the deprecated
  APIs are disabled, the tests will be also disabled, and the
  compilation won't be broken.
