Make two QDT benchmarks data-driven and add more rows

Browse Source 
The QDateTime benchmark's toMSecsSinceEpoch() and
toMSecsSinceEpochTz() each iterated the 2010s and had 1950 and 2050
variants for two other decades. I want to also test some earlier
decades and do similar for create(), so combine the existing triplets
as three rows of a data-driven test for each triplet, add the new rows
and apply the same to create().

In the process, turn an enum used for qint64 constants into a set of
constexpr qint64 declarations.

Pick-to: 6.4 6.3 6.2 5.15
