[ChangeLog][CMake] Private Qt modules have been split off into separate Qt6FooPrivate CMake config packages. A call to find_package(Qt6Foo) will now implicitly find_package(Qt6FooPrivate). It's not an error if Qt6FooPrivate isn't available as it may be the case on certain Linux distros that split their Qt module packages into private and public parts. For every public module Qt6Foo that has an associated Qt6FooPrivate module, create a separate Qt6FooPrivate CMake config package. Let Qt6FooPrivate find Qt6Foo. This is a required dependency. Let Qt6Foo find Qt6FooPrivate if it's available. A message of log level VERBOSE is issued if Qt6FooPrivate is not found. Implementation notes: In QtModuleConfig.cmake.in, we pull in the private module. This is not part of the *Dependencies.cmake file, because 1. The Qt6FooPrivate package references the Qt6::Foo target, therefore it must be available. And Qt6FooDependencies.cmake is loaded before creating targets. 2. The dependency needs to be optional, and we don't have facilities for optional dependencies in Qt6FooDependencies yet. 3. We'd have to avoid recursion, because of the Qt6FooPrivate -> Qt6Foo dependency.
