QTouchEvent::touchPoints() returns a const-&, but the old
code took a copy, over which it then iterated, modifying
the touch points, causing (necessary) detaches of both the
list and the touch points.
Befriend QTouchEvent and modify the list in-place, avoiding
all detaches in the likely case that QTouchPoint contains the
only copy of the touch point list.
This is all the more important as the function is called once
for every item-under-mouse in sendTouchBeginEvent().

Helps pinning the vtable to a single TU, which can
prevent false negative RTTI (incl. dynamic_cast and
catch()).
But mostly because it's rather pointless to have dtors
of polymophic function inline. Most of the time, the
code will be called through the vtable indirection,
anyway (which also means that an out-of-line copy of
the code needs to exist in any case). The inline
method will only be used when the compiler can prove
the dynamic type of an object.

The QMap<QByteArray, QString> was only used to hold key/value pairs
until they were serialized into a QString at the end of the function.
Serialize into QString directly instead, dropping the temporary QMap.
The problem is that we'd like to keep the line formatting central
while at the same time harnessing the power of QStringBuilder.
This is possible with a templated function with an input/output
parameter:
format_attr(QString &result, const char *key, T &&value)
format_attr(result, text-foo, str + str2 + str3);
Or with return type deduction:
formatted(const char *key, T &&value) -> decltype((expr)) { return expr; }
result += formatted(text-foo, str + str2 + str3);
I don't like out parameters, and we can't rely on auto return
type deduction, yet, so I opted for a miniature expression
template solution that can only match the expression
attr[key] = value;
where 'key' is a const char* and 'value' can be anything that
QStringBuilder supports. This allows to keep the syntax of a map
while at the same time serializing to QString immediately.
The only behavioral difference to the old code is that the
attributes are no longer sorted, but order doesn't matter.

By making the destructor (usually the first non-inline, non-pure,
virtual function, and therefore the trigger for most compilers to
emit the vtable and type_info structures for the class in that TU)
out-of-line, vtables and, more importantly, type_info structures for
the class are pinned to a single TU. This prevents false negative
dynamic_cast and catch evaluation.
Since QGraphicsItemPrivate is already exported, users of this class
are unaffected by the change, and since it's private API, we don't
need to avoid adding code to the out-of-line destructor until Qt 6.

[UITextInput textInRange] is sparsely documented, but it turns out that
unconfirmed marked text should be seen as a part of the text document. This
is different from Qt IM (ImSurroundingText), which handles marked text on
the side. The reason we can assume this is that the range we are given
as argument to textInRange exceeds the documents length when having
marked text appended to the end, suggesting that it tries to read / verify
the current marked text. In addition, keyboards like Japanese-Kana will not
update and function correctly unless marked text is included.
Note that the docs seems to imply that you cannot have marked text and text
selection at the same time, unless the selection is contained within the
marked text (using the dedicated selectedRange argument to setMarkedText).
If this turns out to be incorrect, we might need to adjust the methods
dealing with selection to also include marked text as well.
