Make QSignalSpy copy QVariant parameters directly
Previously, a QVariant parameter would be wrapped inside a new
QVariant, and you would have to cast the QSignalSpy's QVariant to
a QVariant to get the actual value. This behavior was unintuitive
and undocumented.
Check if the parameter type is QVariant, and copy it directly if it
is. This makes the QSignalSpy's QVariant directly usable (no need to
"unwrap" the value in user code).
Existing tests that use QSignalSpy together with QVariant parameters
(such as tst_QPropertyAnimation::valueChanged()) and do cast the
QVariant parameter to a QVariant, continue to work after this change;
this is because qvariant_cast<QVariant>() returns its input value
(unchanged) when the type is not QMetaType::QVariant.
