If a type has both a converter to QVariantList and to
QSequentialIterableImpl registered, we would have chosen the
QSequentialIterableImpl version. In the case of types like QJSValue,
this is more costly. With this change we therefore uses the direct
conversion if it has been registered.
The same applies to QAssociativeIterableImpl and
QVariantHash/QVariantMap.

This flag is used in QSequentialIterable and QAssociativeIterable to indicate
that the data pointer in VariantData should be deleted after the variant has
been constructed.
The use case for this is
https://codereview.qt-project.org/c/qt/qtdeclarative/+/284151, where we have
a proxy iterator and cannot easily return a pointer to already owned data, as
it is hard to manage its lifetime in the iterator. In contrast, it is clear
that we can release the memory in the QSequentialIterable functions, as it has
already been copied into the QVariant there.

In almost all cases, use d->allocatedCapacity() or
d->constAllocatedCapacity() instead of d->alloc, since they do the
same thing (right now). In the future, the functions will be
changed. There is a separate const version because most const code
should not need to know the allocation size -- only mutating code
should need to know that
There are a few cases where d->alloc was replaced with a better
alternative, like d->size. The one case that remains in the code will
be replaced by a different test when it's available.

QObjectPrivate::threadData used to be a QThreadData *, and was
read and written from multiple threads without proper synchronization.
As an example, it was read from QCoreApplication::postEvent and
written from QObject::moveToThread, therefore causing UB.
Port threadData to a proper atomic, removing the races. Fix all usage
points.
In general, QObject is documented to be simply reentrant,
not thread-safe, and certain bits (e.g. timers, moveToThread)
are not even reentrant. The reasoning therefore is that a given
QObject's threadData is not supposed to be touched by multiple
threads without some synchronization happening elsewhere, and
therefore relaxed loads should be sufficient.
As drive-by change: refactor QCoreApplication::postEvent.
It was particularly subtle, because it had a loop using a volatile
to cope with the possibility of the receiver object switching thread
while we tried to lock its thread's event queue.
However, volatile does not achieve any synchronization, so drop it,
and refactor the algorithm using better locking primitives.
Put this algorithm in a common place, and also reuse it from
removePostedEvents, which was lacking any synchronization.

In Qt6 QList is just a typedef to QVector. To keep Qt5 behavior
compatibility we need to register aliases, otherwise some type name

The patch doesn't cover usage of already typedef'ed and aliased
QList and QVector, but that should be quite esoteric, especially
after introduction of automatic QList and QVector type registration.
