Fix the syncqt issue when two modules are created in the same
CMakeLists.txt and share the build directory. In this case the
second module in the dependency chain rewrites
'module_headers[_generated]' files, so syncqt is not able to

When submitting applications to the iOS and macOS AppStore the
application goes through static analysis, which will trigger on
uses of various privacy protected APIs, unless the application
has a corresponding usage description for the permission in the
Info.plist file. This applies even if the application never
requests the given permission, but just links to a Qt library
that has the offending symbols or library dependencies.
To ensure that the application does not have to add usage
descriptions to their Info.plist for permissions they never
plan to use we split up the various permission implementations
into small static libraries that register with the Qt plugin
mechanism as permission backends. We can then inspect the
application's Info.plist at configure time and only add the
relevant static permission libraries.
Furthermore, since some permissions can be checked without any
usage description, we allow the implementation to be split up
into two separate translation units. By putting the request in
its own translation unit we can selectively include it during
linking by telling the linker to look for a special symbol.
This is useful for libraries such as Qt Multimedia who would
like to check the current permission status, but without
needing to request any permission of its own.

This is a level A SIC, as it breaks
QFile f = "/some/path";
In general, it's not a good idea to have this implicit conversion. A
QFile is not a representation of a path, so the conversion should be
explicit.
I am going to keep the current semantics (implicit conversion) up to and
including Qt 6.8 (LTS). Starting from 6.9, the constructor will be
unconditionally explicit. This is deliberate, and done in order to make
users fix their code while staying in Qt 6, rather than encountering
this issue (and countless many more) if and when they upgrade from Qt 6
to Qt 7. In the meanwhile, users can opt-in to the new semantics by
defining a macro.
[ChangeLog][QtCore][QFile] The QFile constructors that take a path are
going to become unconditionally `explicit` in Qt 6.9. Code like `QFile f
= "/path";` will need to be ported to equivalent one (e.g. `QFile
f{"/path/"}`). This has been done in order to prevent a category of
mistakes when passing strings or paths to functions that actually take a
QFile. Users can opt-in to this change even before Qt 6.9 by defining
the QT_EXPLICIT_QFILE_CONSTRUCTION_FROM_PATH macro before including any
Qt header.

We currently don't have any machinery for qmake or CMake to map

to the Info.plist CFBundleLocalizations key.
This results in macOS and iOS falling back to the development region,
CFBundleDevelopmentRegion, as the only supported localization of the
app, which is in most cases set to 'en'.
Unfortunately this doesn't work well with the behavior of iOS 11+
and macOS 10.13+ where the OS will set the locale of the app to
the best match between the app's supported localizations and the
user's preferred language.
https://developer.apple.com/library/archive/qa/qa1828/
Since we only support a single localization, the development region,
the locale always ends up as 'en_<REGION>', which after QTBUG-104930
is also reflected in the QLocale's uiLanguages(), resulting in the
QTranslator machinery always picking English translation for the app.
As long as we don't explicitly declare CFBundleLocalizations we need
to opt out of the system's behavior of finding the best match between
the app's declared localizations and the user's preferences, which we
can do via the CFBundleAllowMixedLocalizations key.

In theory we don't need the array to be static and it did compile

MSVC complains that the lambda function below can't access the array.
I don't understand why, because we use [&] in the lambda and it should
capture all the variables in theory, but in reality it failed to
capture this variable in the end. And making the variable static
solves this issue. Maybe it's a MSVC bug.

syncqt.pl adds an extra dependency on perl when building Qt. Modern C++
provides the convenient cross-platform way to access a filesystem and
to use regular expressions, so we may replace the perl script with C++
application. The syncqt executable is built at configure time and
installed as QtCore tool. It's running at configure time to deliver the
required header files for IDE to build a consistent code model and at
the build time to keep tracking changes in header files and generate
the missing aliases without reconfiguring. 'syncqt' only parses header
files from a CMake build tree, so the resulting Qt installation only
contains interfacing headers that belong to the platform that Qt is
built for. 'sync.profile' files are not used as the 'source of truth'
for sync qt procedure anymore, all the necessary information is taken
from either CMake files at configure time or from the module header
files while parsing them.
syncqt.pl is still in place since it's required as fallback solution
for a smooth transition to the new syncqt implementation for all qt
repositories.
This patchset only enables the C++ based syncqt for 'qtbase'
repository.
From the performance perspective C++ version works faster then perl
script, also the configure time is reduced significally on subsequent
reconfigurations - up x2 times faster when re-configuring repository,
but it also takes time to compile the tool itself the first time.
Numbers for qtbase:
syncqt.pl syncqt.cpp
initial: 0m16,035s 0m20,413s
reconfig: 0m6,819s 0m3,725s

Instead of creating the tool wrapper shell script only
during a Qt build in QtBuild.cmake,
ensure it is created any time _qt_internal_wrap_tool_command is
called, regardless if we're building Qt or a user project.
As a transitional period not to break compatibility, we also need
to create the script in QtBuild.cmake, until all usages of
QT_TOOL_COMMAND_WRAPPER_PATH are replaced with function calls.
Currently such usages are present in qtdeclarative.
When considering which bin dirs to add to the script's PATH
environment variable assignment, in addition to the build
internals relative bin dir, also add QT_BUILD_DIR,
QT_ADDITIONAL_PACKAGES_PREFIX_PATH and QT6_INSTALL_PREFIX.
QT_BUILD_DIR is important so we always pick up the just-built
but not installed libraries in a prefix build when running just-built
tools.
QT_ADDITIONAL_PACKAGES_PREFIX_PATH is important when building examples
as ExternalProjects in prefix builds, to ensure that the
not-yet-installed tools and libraries are picked up from the repo
build dir, which is passed via QT_ADDITIONAL_PACKAGES_PREFIX_PATH
to the external projects.
QT6_INSTALL_PREFIX is there in case if the build internals relative
dir is located in a different places than the Qt6 package.

Move it into QtPublicCMakeHelpers.cmake so it is available also when
configuring qtbase and the Qt6Config.cmake file is not yet loaded.
