CMake: Allow finding Qt CMake packages in additional locations By default, when using the Qt6 CMake package to look for components, the find_package() calls for the components use NO_DEFAULT_PATH to ensure that CMake doesn't accidentally find system (distro) packages. Instead we limit the paths to one level up from where the Qt6 package is. Unfortunately that doesn't quite work for finding Qt packages that might have been installed into a different prefix than where the main Qt prefix is. This happens when Qt addons are built by Conan, and installed into a separate prefix. To allow calls like find_package(Qt6 COMPONENTS ConanAddon) to work in a scenario as described above, introduce a new variable called QT_ADDITIONAL_PACKAGES_PREFIX_PATH which can be used to specify additional paths where Qt CMake packages should be found. This is similar to previously introduced QT_EXAMPLES_CMAKE_PREFIX_PATH variable which was meant for a similar case, but only for examples. Additionally, allow disabling the NO_DEFAULT_PATH option by setting the QT_DISABLE_NO_DEFAULT_PATH_IN_QT_PACKAGES cache variable to TRUE. This would allow regular usage of CMAKE_PREFIX_PATH to work, at the risk that system Qt CMake packages might be found.

Merge main and private targets of the internal modules In cmake, targets are used as an entity for modules. This causes a number of problems when we want to manipulate a module as a separate entity with properties associated with it. The _qt_internal_module_interface_name target property is introduced to represent the module entity. All modules write a name to this property, which will subsequently expand into the module name matched with the module name in qmake. The 'qt_internal_module_info' function is responsible for providing the correct values ​​for the module properties used when working with a module target. Unlike qmake, for internal modules in cmake it is expected that the Private suffix will be specified explicitly. In case the user wants to have a different module name, an additional argument MODULE_INTERFACE_NAME of the qt_internal_add_module function is introduced. This also changes the way how target dependencies are collected and resolved. Since the 'Private' suffix no longer means an unique identifier of the module 'Private' part, we look for the both Private and non-Private package names when resolving dependencies. TODO: This change doesn't affect the existing internal modules, so to keep compatibility with the existing code the existing internal modules create 'Private' aliases. The code that provides backward compatibility must be removed once all internal modules will get the proper names.
