It's not sufficient to pass -I{prefix}/include when doing the header
clean check.
We need to propagate all target include directories and compile
definitions, and also the compile flags for good measure.
For macOS frameworks we also need to explicitly pass an -iframework
flag (qmake passses -F instead), to ensure that <QtGui/qfoo.h> style
includes are found when building other repos than qtbase.

This ensures ccache or sccache is used to cache the compilation of the
headerclean checks.

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.

Having ${QT_BUILD_DIR}/include as include path is not enough for
modules outside of qtbase. They also need to pick up headers from e.g.
Qt Core, which are available only in "${CMAKE_INSTALL_PREFIX}/include"

C4180, C4458 were disabled already in 2012, in commit 6668f5becf.
C4577 was disabled due to QtScript being compiled without exception
support in commit 97d7d80e73.
Anyhow, Qt Script is now officially gone in Qt 6, and Qt headers
do work just fine with C4180. Finally, C4458 is nowadays a W4 warning,
so not enabled in the first place.

Configure Qt with -DQT_FEATURE_headersclean=ON to enable the
check. There will be separate target for each module include
(e.g. QtCore_header_check), but the check will also be done
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
builds; the qmake code path did never enforce that on CI
machines (it was non-Apple clang only), and the check currently
fails on these configurations.
