Joerg Bornemann ad7b94e163 CMake: Only load Qt6FooPrivate automatically when building Qt 
[ChangeLog][CMake] CMake packages of public Qt modules don't provide the
targets of their private counterparts anymore. User projects must now
call find_package(Qt6 COMPONENTS FooPrivate) to make use of the
Qt6::FooPrivate target. User projects that rely on the old behavior can
set the CMake variable QT_FIND_PRIVATE_MODULES to ON.

For user projects, the warning message we know from QMake is displayed.
The warning can be disabled by setting the CMake variable
QT_NO_PRIVATE_MODULE_WARNING to ON.

Within Qt itself, find_package(Qt6Foo) will still
find_package(Qt6FooPrivate).

For static Qt builds, we need to wrap usage of private Qt modules in
$<BUILD_INTERFACE> or $<BUILD_LOCAL_INTERFACE> (if CMake's version is >=
3.26). Static builds with CMake < 3.26 will always load the private
modules if the Qt6FooConfig.cmake from Qt's build tree is loaded. This
is the case in non-prefix builds and (in the future) when building
examples as external project.

This amends commit fbbf4ace0188b9718b6d7808021c0b887fd52d9f.
