This also adds image conversion of both format and color space, which
will also be required later for conversions to CMYK formats and color
spaces.

Follow the established convention that byte-oriented image formats
have the "8888" suffix, not "32". The old enum name is temporarily
left to help port other submodules.

This commit adds a CMYK 8bpp format to QImage. The idea is to enable the
transport of CMYK images inside Qt, for instance to be loaded/saved from
files or painted on CMYK capable paint devices (e.g. PDF).
Also, rasterization support *from* a CMYK image is added (on top of a
RGB surface), as well as CMYK image scaling/conversion.
Conversion and rasterization between CMYK and RGB isn't particularly
optimized nor it honors any colorspaces yet. The overall idea is to
match 1:1 the existing behavior of CMYK QColor (which get naively
changed to RGB; there isn't colorspace support in QPainter yet).
There are no plans to add rasterization *towards* CMYK.
Image save/load in native CMYK formats will be added in future commits.
This work has been kindly sponsored by the QGIS project
(https://qgis.org/).
[ChangeLog][QtGui] Support for 8-bit CMYK images has been added.

qExchange is one of the few remaining functionalities that have not been
moved out of qglobal. Given that std::exchange exists in the standard, we
can simply move to it everywhere...
...if it weren't for the fact that std::exchange is only constexpr in
C++20, and only has its noexceptness specified in (most likely) C++23.
Still, we want to move to the existing std functionality where
possible, to allow the removal of qglobal includes in lieu of something
more fine-grained in the future.
So leave any constexpr calls[1] alone for now (and observe that none of
our current usages cares about the conditional noexceptness), but
replace everything else.

Instead of using the overly-generic qSwap() monster, use
- qt_ptr_swap() for swapping raw pointers
- member-swap for swapping smart pointers
- std::swap() for swapping scalars
In QtCore, this has proven to give a nice reduction in compile time
for Qt users, cf. b1b0c2970e480ef460a61f37fa430dc443390358.

Handy when one has the data buffer to be read in a QBAV.
This also fixes an issue and compiler warning about passing a
qsizetype data length value as an int, and makes it possible to pass
a qsizetype-size length without going through QByteArray.
Makes the QByteArray overload redundant.

At the moment we have two main strategies for dealing with move
assignment in Qt:
1) move-and-swap, used by "containers" (in the broad sense): containers,
but also smart pointers and similar classes that can hold user-defined
types;
2) pure swap, used by containers that hold only memory (e.g. QString,
QByteArray, ...) as well as most implicitly shared datatypes.
Given the fact that a move assignment operator's code is just
boilerplate (whether it's move-and-swap or pure swap), provide two
_strictly internal_ macros to help write them, and apply the macros
across corelib and gui, porting away from the hand-rolled
implementations.
The rule of thumb when porting to the new macros is:
* Try to stick to the existing code behavior, unless broken
* if changing, then follow this checklist:
* if the class does not have a move constructor => pure swap
(but consider ADDING a move constructor, if possible!)
* if the class does have a move constructor, try to follow the
criteria above, namely:
* if the class holds only memory, pure swap;
* if the class may hold anything else but memory (file handles,
etc.), then move and swap.
Noteworthy details:
* some operators planned to be removed in Qt 6 were not ported;
* as drive-by, some move constructors were simplified to be using
qExchange(); others were outright broken and got fixed;
* some contained some more interesting code and were not touched.

Fix our API, so that QStringList and QList<QString> are the
same thing.
This required a bit of refactoring in QList and moving the
indexOf(), lastIndexOf() and contains() method into
QListSpecialMethods. In addition, we need to ensure that
the QStringList(const QString&) constructor is still available
for compatibility with Qt 5.
Once those two are done, all methods in QStringList can be moved
into QListSpecialMethods<QString>.
