CMake: Create aliases for Internal targets using common function

Previously we did not create Qt6:: namespaced aliases.
This is needed as a workaround preparation for getting the package name
of a module target from one of it's properties.

Before it would fail in qtinterfaceframework because
ifvehiclefunctions-simulation-server uses PUBLIC_LIBRARIES
in its qt_internal_add_app call, and because _add_app does not handle
such an option, some weirdness in qtbase's _add_app -> _add_executable
-> _extend_executable -> _register_target_dependencies ended up trying
to register PlatformAppInternal as package dependency.
That issue will be handled in separate changes.

Pick-to: 6.4
Task-number: QTBUG-104998
