QTimer::singleShot is optimized for zero timeouts when using the API
taking a string method name. This optimization was not used for the API
taking a PMF or functor. This patch adds it, making the various API
calls behave similarly from a performance point of view.
The approach taken here requires a QObject context object. If none is
available, e.g. a nullptr was passed explicitly, or the
QTimer::singleShot(O, Functor) API was used, the optimization could
not easily be applied. This is not only bad from a performance POV,
but also poses as a potential source for heisenbugs: Using the
different API versions of QTimer::singleShot would use different code
paths internally, which then would not ensure the expected slot call
order. This problem actually existed already when mixing the
string-based slot syntax with PMF/functors in the QTimer::singleShot
API.
This patch overcomes this hurdle and fixes all of the above: When we
encounter a 0ms single shot timer, and no QObject context object is
available, we fall back to the main thread, or create a temporary
QObject for any other thread. The updated and extended benchmark
shows that this is still a significant performance improvement
over using a timer:

Additionally, this patch adds a unit test to verify that the slot call
order for 0ms single shot timers is followed while mixing the various
API versions. It fails without this patch but passes now.
Finally, another test is added to verify that using QTimer::singleShot

In Korean text, they typically can use both the "Western" style of
word wrapping, i.e. breaking on spaces, as well as the East-Asian
style of potentially breaking between all syllables. However,
the Unicode Line Breaking Algorithm, TR14 defaults to breaks on
syllables and specifies a possible tailoring where Hangul is
mapped to the AL class instead:
"When Korean uses SPACE for line breaking, the classes in rule
LB26, as well as characters of class ID, are often tailored to AL"
When using Qt, the user would expect the WordWrap wrap mode to
break between words in Korean. If you want the syllable-based
text layout, you would use WrapAnywhere, probably accompanied
by line justification.
To avoid breaking QTextBoundaryFinder and other potential clients
of QUnicodeTools which depend on getting the precise Unicode
data from the algorithm, we do this by passing a flag from
QTextEngine when initializing the attributes. This way, it
can also be made optional later on, if we decide there is
a reason to add an additional wrap mode specifically to
handle cases like this.
[ChangeLog][Important Behavioral Change] WrapWord now
correctly prefers line breaks between words in Korean text.
WrapAnywhere can still be used to get breaks between syllables
instead.

9204b8c31e broke font matching on Windows.
After this change, if you request a specific face of a family, such
as "Arial Black", and Qt detects that its typographic/preferred name
is "Arial", then it will be added as the single style of the Arial family,
which will in turn be set as populated=true.
So if you later request a regular font of "Arial" family, then it will
see that the family has already been populated, skip this step, and
then see that there is only one style available, i.e. "Arial Black".
To work around this, we need to make sure the typographic family is
properly populated the first time it is registered.

to request different faces of a font family after a specific type face
