Replace most use of QVariant::type and occurrences of QVariant::Type

I made a clazy automated check that replaced the use of QVariant::Type
by the equivalent in QMetaType.
This has been deprecated since Qt 5.0, but many uses were not yet removed.

In addition, there was some manual changes to fix the compilation errors.

Adapted the Private API of QDateTimeParser and QMimeDataPrivate
and adjust QDateTimeEdit and QSpinBox.

QVariant(QVariant::Invalid) in qstylesheet made no sense.

But note that in QVariant::save, we actually wanted to use the non-user type.

In the SQL module, many changes were actually reverted because the API
still expects QVarient::Type.
