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.

Now that we run tests for static Qt builds in the CI, it makes sense
to restore the CMake build tests that check that static plugin
importing works correctly.
Resurrect the previously commented out test_import_plugins project and
port the mockplugins qmake projects to CMake.
mockplugins is a CMake project that uses the internal Qt CMake API to
build and install some Qt modules and plugins.
test_import_plugins depends on that test (via a CMake fixture) to
build public projects that use those plugins.
The installation of the mockplugins modules pollutes the Qt install
prefix, but in the CI that only happens on the test VM, which means
the release packages are not affected.
Locally on a developer machine the Qt install path will be polluted,
but it's not that much of a big deal. We could try and address that in
a future change by using the QT_ADDITIONAL_PACKAGES_PREFIX_PATH
functionality added for Conan to allow the installation of Qt packages
into a non-standard prefix.
