By not explicitly disabling min/max macros of `windows.h`, we may see
some unintended substitutions. This is especially important now that we
are moving toward enabling Unity Build, and some of the constructs for
manually dealing with this issue, eg., `#ifdef max`, `#undef max`, might
not make it to the pool, and as a result we get build failure.

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
The syncing procedure can be run separately for each module using
<ModuleName>_sync_headers targets. The 'sync_headers' target can be
used to sync all the modules at once.

When building a Qt module against an installer-provided Qt on macOS, the
module pulls in the headersclean feature that creates the *_header_check
targets. Those targets try to compile the public headers of the module,
and the compilation command contains the -iframework argument. That
-iframework argument is supposed to point to the directory where the Qt
libs are installed. However, it pointed to the original
CMAKE_INSTALL_PREFIX of the machine where Qt was packaged.
Use the QT_BUILD_INTERNALS_RELOCATABLE_INSTALL_PREFIX variable instead
that contains the real installation location, even for an
installer-provided Qt.

Before CMake 3.19, we are not allowed to query non INTERFACE_ prefixed
property names from INTERFACE libraries. And it was the wrong thing
to do as well. Prefix the properties with INTERFACE_ as appropriate.
Don't try to add INTERFACE_COMPILE_DEFINITIONS from header only
modules to the headerclean compile commands. This causes configuration
issues with UiPlugin in qttools. Fortunately it seems that qmake
doesn't do that for 'header_module's either.
Finally don't query for the FRAMEWORK property on the passed target
(INTERFACE libs can't be frameworks). Instead just query if the whole
Qt build itself is a framework build.
An issue was discovered regarding QT_NO_ENTRYPOINT genexes breaking
headersclean add_custom_commands for UiPlugin in qttools. To avoid
this the property was renamed to all lower case in
6ca66de9120537134b63d42de6c53c6e5834e8f3. This avoided the immediate
issue, but it's possible it might resurface in the future with a
different property name that wasn't renamed. In particular I thought
it might happen with QT_NO_UTF8_SOURCE but it didn't.
In case something like that happens again, the two possible solutions
are to bump minimum CMake version requirement to 3.19 (where upper
case property names are allowed to be queried from INTERFACE libs) or
to implement recursive include directory fetching similar to our
qt_internal_walk_libs implementation.

It appears there's a difference between the chosen macOS compiler path
in the CI versus the compiler path on my local machine.
In the CI the chosen compiler path ends up 'being /usr/bin/clang++'
whereas for me locally it's
/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/c++
For some reason the headersclean commands succeed in the CI, but
locally they fail for me saying that standard library includes can not
be found, unless an explicit sysroot flag is specified.
I assume that in the CI the '/usr/bin/clang++' compiler shim chooses some
implcit sysroot, whereas the longer Xcode compiler expects an explicit
sysroot.
It's probably also affected by the fact that in the CI we pass an
explicit CMAKE_OSX_SYSROOT to a non-standard Xcode location e.g.
/Applications/Xcode11.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.15.sdk
Note the '11' in the Xcode app name.
Locally I don't pass a custom CMAKE_OSX_SYSROOT, and my Xcode is
installed in a regular location e.g /Applications/Xcode.app.
The sysroot flag and path is added to regular CXX compilation rules
inside CMake's core (in cmLocalGenerator.cxx).
Reuse the same variables that CMake uses and add them to our headersclean
command rules.

Configure Qt with -DQT_FEATURE_headersclean=ON to enable the

when the module is built for the first time.
There are notable differences to the qmake version:
- the build does not pick up anymore default defines or flags from
the module, or Qt. Instead options like -fPIC they have to be listed
explicitly. Also for this reason, we have to skip the vulkan-related
headers from the check, since vulkan/vulkan.h is not necessarily
in the compiler's default search path.
- some checks for nowadays unsupported compiler versions are
removed.
- -Wdouble-promotion -Wshorten-64-to-32 is not added for clang
