Add the CONFIG value c++2b that represent the upcoming C++23 standard.
Add QMAKE_CXXFLAGS_CXX2B and QMAKE_CXXFLAGS_GNUCXX2B.
On MSVC, use /std:c++latest when c++2b is active.
This fixes an issue with MSVC where c++latest implied the /std:c++20

Before this change, configure -force-asserts would affect qmake-based user
projects too, potentially forcing the user to remove the
QT_FORCE_ASSERTS define in their own projects.
[ChangeLog][configure] The -force-asserts option now affects the Qt
build only, not user projects.

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.

For prefix builds the prl files of header modules still contained the
absolute path of the install prefix instead of $$[QT_INSTALL_LIBS]. This
was, because the QMAKE_PRL_INSTALL_REPLACE variable was only filled for
'lib' TEMPLATE projects. Header modules, however, have the 'aux'
template.

For every executable that uses a static Qt library (e.g. rcc using

This was because we've built all libraries with -fvisibility=hidden
-fvisibility-inlines-hidden but not the executables linking against
them. On macOS however, all translation units must have the same
visibility setting.
We're now setting the same visibilty for libs and executables on

QMAKE_PRL_LIBS contains absolute paths to libraries, e.g. libqtpcre2.a.
On "make install" the libdir is replaced with the installation target
libdir. If the libdir is in QMAKE_DEFAULT_LIBDIRS (e.g. /usr) then the
replacement was empty. That worked fine for include paths but not for
paths referencing files in that libdir:
/my/build/lib/qtbase/lib/libqtpcre2.a would become /libqtpcre2.a.
Add another replacement that takes care of file paths and inserts
$$[QT_INSTALL_LIBS].

This was originally enabled in the mkspecs for 64-bit QNX 7.0.0
but that broke when the qtConfig change was made. It looks like
qtConfig shouldn't be used in the platform mkspecs. I suspect
the stack-protector changes were left out of the 32-bit mkspecs
so that 6.6.0 builds wouldn't be affected.
Ignore the stack-protector/stack-protector-all possibility since
it isn't possible to access it without a command line option.
Specifying both options doesn't even make sense since
stack-protector-all encompasses stack-protector.
For now, leave out command line control of this feature.
