In Qt 5, QVariant::isNull() was true when the contained object had an
isNull() that was true; this is no longer true in Qt 6, so we now have
QSqlResultPrivate::isVariantNull() to test is-or-contains
null. However, for date-times, QSqlDriver::formatValue() treats
invalid QDateTime as NULL, since it needs its toString(Qt::ISODate),
which will be empty if invalid. As QDateTime's isValid() is more
stringent than its !isNull(), this can lead to one that's neither
valid nor null, such as QDateTime(QDate(), QTime(0, 0)), producing an
invalid entry in a database.
Do the same for QTime, as its isValid() is more stringent than
!isNull(), and its toString() likewise returns empty on invalid
(although it's not clear it's possible to construct one that's neither
valid nor null). For QDate valid and null are simply complementary.
[ChangeLog][QSql] Handling of QDateTime and QTime values passed to SQL
now consistently treats invalid as null. Some values of these types
are neither valid nor null, which could lead to invalid data being
given to the SQL database. Invalid values are now treated as null to
prevent this.

In Qt 5, QVariant::isNull returned true if either the variant didn't
contain a value, or if the value was of a nullable type where the type's
isNull member function returned true.
In Qt 6, QVariant::isNull only returns true for variants that don't
contain a value; if the value contained is e.g. a null-QString or
QDateTime, then QVariant::isNull returns false.
This change requires a follow up in the SQL drivers, which must
still treat null-values the same as null-variants, lest they write data
into the data base.
Add a static helper to QSqlResultPrivate that implements isNull-checking
of variants that contain a nullable type relevant for Sql, and add a
test case to the QSqlQuery test that exercises that code.

QSqlQuery is a broken value class. Copying one object would mean
copying database state (the result set, the cursor position, etc.)
which isn't generally available for all database drivers.
For that reason, the current implementation does not honor value
semantics -- modifying a QSqlQuery object has visible side effects
on its existing copies (!).
The correct solution is to accept that QSqlQuery is a move only
type, not a value type. Add move semantics to it, and deprecate
its copies.
(We can't just *remove* copies in Qt 6 due to SC/BC constraints).
[ChangeLog][QtSql][QSqlQuery] QSqlQuery copy operations have
been deprecated. QSqlQuery copy semantics cannot be implemented
correctly, as it's not generally possible to copy a result set
of a query when copying the corresponding QSqlQuery object. This
resulted in modifications on a QSqlQuery having visible (and
unintended) side effects on its copies. Instead, treat QSqlQuery
as a move-only type.
