185cba6e95 Replace qdebug.h includes in public headers with forward-declarations
qdebug.h includes many Qt and STL headers, so if you include a Qt header
you get all those transitive includes, which may affect build time.

- Where appropriate use the printf-like syntax of qDebug() and co.,
  these don't need the QDebug streaming operators
- qfloat16 is used in an inline member function, so include it
  explicitly

[ChangeLog][Potentially Source Incompatible Changes] Various Qt public
headers don't include QDebug any more; if you need QDebug's streaming
you'll have to include it in your code.

3b30b0fc2e CMake: Add deployment API to our examples
Projects were modified using the tool at:
https://git.qt.io/alcroito/cmake_refactor

A couple of examples had to be adapted manually, due to them including
more than one app per example subdirectory.

The INSTALL_EXAMPLESDIR and INSTALL_EXAMPLEDIR assignments were
removed.

The install(TARGETS) calls were modified according to our
documentation snippets for qt_generate_deploy_app_script.

A qt_generate_deploy_app_script call was added for each executable
target.

Note that the deployment step will be skipped in the CI for now,
because we enable QT_DEPLOY_MINIMAL_EXAMPLES and thus
QT_INTERNAL_SKIP_DEPLOYMENT, and also because standalone examples
are not enabled yet, and deployment is disabled for in-tree (so
no-standalone-example) prefix builds.

The install(TARGETS) calls for each example will still run,
installing the examples into an installed_examples directory, that
will not be archived by the CI.

aa37e67ef7 Port from qAsConst() to std::as_const()
We've been requiring C++17 since Qt 6.0, and our qAsConst use finally
starts to bother us (QTBUG-99313), so time to port away from it
now.

Since qAsConst has exactly the same semantics as std::as_const (down
to rvalue treatment, constexpr'ness and noexcept'ness), there's really
nothing more to it than a global search-and-replace, with manual
unstaging of the actual definition and documentation in dist/,
src/corelib/doc/ and src/corelib/global/.

7a7023b7b1 Chip example: fix an accidental bool->int conversion when using PMF connections
The example was refactored to use the PMF connection syntax.
However this introduced a problem: when connecting a QAbstractButton
to a slot that has a default parameter, the semantics of the connection
change between string-based connections and PMF.

Specifically: when connecting the

  QAbstractButton::clicked(bool checked = false)

signal to a slot like

  View::zoomIn(int level = 1)

then a string-based connection like

  connect(button, SIGNAL(clicked()), this, SLOT(zoomIn()))

would call zoomIn without carrying the signal's parameter over.
In other words, zoomIn's parameter is defaulted. The same connection
using PFM instead is

  connect(button, &QAbstractButton::clicked,
          this, &View::zoomIn)

which would "connect" the arguments. This makes emissions that pass
false as clicked's parameter result in a zoomIn by 0.

Fix it by avoiding the default parameter of zoomIn -- just split
the function in two (zoomIn and zoomInBy).

Amends 8cf812231405e011b422a1505d9a219618fe5cee.

d97fd7af2b Build examples in isolated sub-builds using ExternalProject
Examples are intended to show how to build against an installed Qt.
Building them as part of the main build means the way the Qt targets
are defined and created are not representative of an end user's build.
By building them as separate projects using ExternalProject, we can
more closely replicate the intended audience's environment. This
should allow us to catch more problems earlier.

Having examples built as part of the main build also creates problems
with some static builds where a tool built by the main build is needed
during configure time. This happens with other repos like qtdeclarative
but not (currently) with qtbase. Converting the examples in qtbase to
be built using ExternalProject is intended as a demonstrator for how
other repos can do similar. Until other repos are converted, they will
continue to work as they did before, with examples as part of the main
build for non-static builds only.

The new build-externally behavior is only supported for non-prefix
builds with this change. Prefix builds will continue to use the old
non-external method. Support for building examples externally in
prefix builds will be a separate change.
