For built-in types, this is a compile-time assert - we should not have
any types in Qt for which we have neither debug streaming nor a
QTest::toString specialization implemented. A build of most of Qt
submodules passes with this change, after minor modifications to some
tests. We cannot declare QSizeHint::Policy as a metatype after the
QMetaType has already been instantiated for it, and the QDebug stream
operator for QElaspedTimer needs to be correctly declared within the
namespace.
Add a self-test function for a custom type, and update reference files
of the self-test.

QString has several functions taking a QRegularExpression: indexOf(),
contains(), and so on. Some of those have an out-argument of type
QRegularExpressionMatch, to report the details of the match (if any).
For instance:
QRegularExpression re(...);
QRegularExpressionMatch match;
if (string.contains(re, &match))
use(match);
The code used to route the implementation of these functions through
QStringView (which has the very same functions). This however opens
up a lifetime problem with temporary strings:
if (getString().contains(re, &match))
use(match); // match is dangling
Here `match` is dangling because it is referencing data into the
destroyed temporary -- nothing is keeping the string alive. This is
against the rules we've decided for Qt, and it's also asymmetric with
the corresponding code that uses QRegularExpression directly instead:
match = re.match(getString());
if (match.hasMatch())
use(match); // not dangling
... although we've documented not to do this. (In light of the decision
we've made w.r.t. temporaries, the documentation is wrong anyways.)
Here QRE takes a copy of the string and stores it in the match object,
thus keeping it alive.
Hence, extend the implementation of the QString functions to keep a
(shallow) copy of the string. To keep the code shared as much as
possible with QStringView, in theory one could have a function taking a
std::variant<QString, QStringView> and that uses the currently active
member. However I've found that std::variant here creates some abysmal
codegen, so instead I went for a simpler approach -- pass a QStringView
and an optional pointer to a QString. Use the latter if it's loaded.
QStringView has some inline code that calls into exported functions, so
I can't change the signature of them without breaking BC; I'm instead
adding new unexported functions and a Qt 7 note to unify them.

This adds support for additional codecs to QStringConverter when ICU is
available.
We store the converter in the state (d[0]), and its canonical name in
d[1]. We need the name there, as in the clear function we close the
UConverter, and set the pointer to null. Consequently, the actual
conversion functions might need to re-open the converter again. The
advantage of this approach is that clear is used in the destructor of
State, and with this approach we properly clean up the state.
There is however a disadvantage: The clear function was so far also used
for resetting the state when QStringConverter::resetState . Discarding
the whole Uconverter for that is however rather costly. For that reason
we modify resetState to call a new function, State::reset. For existing
converters, it behaves the same as clear; for the ICU based converter,
we call the more efficient ucnv_reset. Code compiled against Qt 6.4 can
benefit from this more efficient version; code compiled against older Qt
versions will continue to work, as the conversion functions can just
recretate the converter from the name.
We can distinguish between ICU and non-ICU converters by checking if the
UsesIcu flag is set.
QStringConverter::name is changed to return the name stored in d[1]. The
interface of the ICU converter has a dummy name, so code using the old
name function from QT < 6.4 still returns something, namely a message
asking the user to recompile.
The function is moved out of line, as we need to check for the private
ICU feature, and want to avoid having that check in the public header.
As the QStringConverter ctor taking a name now can allocate memory, it
can no longer be noexcept. Removing the noexceptness is safe, as it was
only added after Qt 6.3.
Note that we cannot extend the API consuming or returning Encoding, as
we use Encoding values to index into an array of converter interfaces in
inline API.
Further API to support getting an ICU converter for HTML will be added
in a future commit.
Currently, the code depending on ICU is enabled at compile time if ICU
is found. However, in the future it could be moved into a plugin to
avoid a hard dependency on ICU in Core.

[ChangeLog][QTestLib] QCOMPARE now evaluates toString() on its

by Qt. If you specialized qCompare() for your own types, then you
need to change its implementation in line with Qt's own qCompare()

[ChangeLog][QTestLib] QCOMPARE calls with nullptr argument(s) will

Previously it was not like that because of the compareHelper()
overload in qtestresult.cpp that treated the presence of
nullptr-arguments as a reason to ignore formatFailMessage() call.
New implementation does not have this check, and correctly
executes formatFailMessage() for all arguments.
Note that the qCompare() overloads that call QTestResult::compare()
internally were not affected by this patch, because they already
defer toString() invocation until the comparison fails.

I checked how this change affects the test execution. The idea was
to pick some tests for types that do not have a specific
