QHostInfo: destroy the result emitter in its own thread

QHostInfoRunnable holds a QHostInfoResult that belongs to the receiver's
thread, but QThreadPool deletes the runnable in one of its own threads,
so that QObject was destroyed from the wrong thread. ThreadSanitizer
reports it as a race on the emitter's vptr, against a receiver being
destroyed at the same time: it fires in tst_qobject's
threadSignalEmissionCrash, where ~QHostInfoResult races with ~QTcpSocket.

Hold it by pointer, and hand it back to its own thread via deleteLater()
when we are not already there. That only works while the thread still has
an event dispatcher to run the deferred delete, so check for one first and
destroy the emitter right away when there is none. This is the situation
at application exit: ~QCoreApplication() clears the main thread's event
dispatcher and only then emits destroyed(), which is what makes the thread
pool finish its runnables.

The emitter keeps its QThreadData alive, but not the QThread, which its
own thread may be destroying while we look at it, so read the dispatcher
and the thread from the QThreadData instead of dereferencing the QThread.

The autotest covers the case of a receiver thread without event dispatcher.

QLocalTime: remove unneeded narrowing conversion

The old code first assigned epoch.remainder (a qint64 variable) to an
int variable, just to widen it again to qint64 for the call to
secondsAndMillisOverflow(). In particular, it Q_ASSERTed the range
_after_ narrowing, so potentially misses actual out-of-range cases.

Use auto to avoid the narrowing.

QWindows11Style: Honor custom text color in palette for TabBarTabLabel

Custom text color set in a palette was not honored in the
QWindows11Style for the CE_TabBarTabLabel, this patch checks, if a
custom color was set in the palette and uses the custom color instead of
the WinUI3 colors.

rhi: gl: Disable vert.attr.locs always

...in endFrame(), not only on WebGL. Is turns out
even QPainter's OpenGL paint engine gets confused if
some QRhi-based OpenGL rendering leaves vertex attribute
