QDateTimePrivate refactor: static'fy the date/time manipulators

This commit moves QDateTimePrivate functions setTimeSpec, setDateTime,
getDateTime, checkValidDateTime and refreshDateTime outside the
class. Like the previous commit, this is done in preparation for the
"Short QDateTime Optimization" as the "msecs" field will be placed in
the short data, if possible.

By making them file-level static, this also improves code generation, as
the compiler doesn't know whether it has to emit the class members for
out-of-line use or not.
