d962c9ff85 CMake: Make Platform a dependency for all Qt internal targets
In particular that influences BundledLibrary targets.

Most internal targets already depended transitively on Qt::Platform
via Qt::Core as a public dependency. This was not the case for
BundledLibrary targets which don't link to Qt::Core.

This led to compilation issues in user projects when targeting
WebAssembly, due to mismatched flags between a bundled Harfbuzz vs
a user project. Probably other subtle issues as well (e.g. none of the
Windows specific compile definitions were passed to bundled libs).

Bundled libraries depend on PlatformCommonInternal already, so make
PlatformCommonInternal turn depend on the public Platform target.
I thought that was already the case, but we merely relied on the
Qt::Core dependency.

Note that Qt::Core should still list Platform as a public dependency,
so it gets propagated to user projects.

e425a2a4b8 Tune compilation flags to reduce libraries size
Add '_WINDLL' definition for the MSVC compilers family.
Check the 'FEATURE_optimize_size' value before replacing compiler flags
in the qt_internal_add_optimize_full_flags function. This is required,
because Qt::Core and Qt::Gui modules lost their ability to shrink,
when selecting the appropriate build type or features.

886db3a2f3 MSVC: Enable control flow guard for release builds
This makes the applications and libraries more safe
and won't cause any binary incompatibility.

It's not supported for MSVC 2015, but since we only
support MSVC 2019 or later in Qt6, it's safe to use
this parameter.

The "-guard:cf" parameter is supported by clang-cl
and intel-cl as well, MinGW doesn't support it.

f27f9e7bd3 MSVC: enable identical COMDAT folding for release builds
According to Microsoft's docs, /OPT:ICF is enabled by the
linker by default unless /OPT:NOICF or /DEBUG is specified.

If we are in RelWithDebInfo mode, /DEBUG is passed to the
linker to generate debug symbols, however, it caused the
identical COMDAT folding be disabled. We now pass /OPT:ICF
to the linker explicitly to prevent this.

3e13fd43df cmake: Always add -Wno-ignored-attributes for clang targeting windows
This matches how it is in the qmake mkspec, silencing a lot of
warnings - but contrary to when building with qmake, it's only
applied when building Qt itself. For external projects built with
cmake, the Qt headers are included with -isystem, which silences any
warnings from those headers.

1048d83fc2 Limit OpenGL deprecation silencing on Apple platform to Qt itself
Apple deprecated the entire OpenGL API in favor of Metal, which
we are aware of, so we don't need to see the warnings when building
Qt.

Instead of applying the silencing globally for all Qt consumers,
both internal and external, we now limit the silencing to Qt itself.
That means user code that explicitly uses any of the deprecated APIs
will see the warnings. Note that this does not apply to merely using
any of the Qt OpenGL APIs. The user has to explicitly use the platform
APIs that have been deprecated.

The warnings need to be disabled on a build system level, so that
that they are passed as -D flags on the command line. If the defines
were done in Qt headers (qguiglobal.h e.g.), they would require the
user to always include this header before any of the Apple headers.

6a47e1c4ee CMake: Propagate largefile flags to all internal consumers
The large file flags in qmake land are set in the
mkspecs/features/unix/largefile.prf file, which is loaded by qmake
when a CONFIG += largefile entry is written by configure into
qmodule.pri.

This essentially makes them global flags for all private Qt targets
because qmodule.pri is a global file loaded load(qt_build_config)

Thus assign the flags onto the PlatformCommonInternal target instead
of the PlatformModuleInternal one.

One peculiarity though is that in qmake land these flags are also
applied when building examples as part of the main Qt build. This
is because qt_build_config loads qmodule.pri even for an example,
because qmake sees it as part of the overall Qt build.
The flags are not applied by qmake if the example is built in
a different standalone build dir not part of the Qt buil dir.

We don't do that in the CMake build, and thus examples will never
have those flags.

f000685612 Add support for skipping warnings are errors
Unfortunately not all repositories are marked as warning_clean
in their .qmake.conf files. For instance qtconnectivity and
qttools are not warning clean. Therefore we need to skip
warnings_are_errors flags on all targets created in that repository.

Add support for skipping the warnings are errors flags, by setting
a QT_SKIP_WARNINGS_ARE_ERRORS property on a target, and use that
within a generator expression with all the accumulated flags.

To mimic behavior of qmake, and set the property on all targets
created by add_qt_module, add_qt_plugin, etc, one simply needs
to set the QT_REPO_NOT_WARNINGS_CLEAN variable in the
repo project CMakeLists.txt.
