Alexey Edelev 425ff34aa1 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.

# This is the main entry function for creating a Qt module, that typically
# consists of a library, public header files, private header files and configurable
# features.
#
# A CMake target with the specified target parameter is created. If the current source
# directory has a configure.cmake file, then that is also processed for feature definition
# and testing. Any features defined as well as any features coming from dependencies to
# this module are imported into the scope of the calling feature.
#
# Target is without leading "Qt". So e.g. the "QtCore" module has the target "Core".
#
# Options:
# NO_ADDITIONAL_TARGET_INFO
# Don't generate a Qt6*AdditionalTargetInfo.cmake file.
# The caller is responsible for creating one.
#
# MODULE_INTERFACE_NAME
# The custom name of the module interface. This name is used as a part of the include paths
# associated with the module and other interface names. The default value is the target name.
# If the INTERNAL_MODULE option is specified, MODULE_INTERFACE_NAME is not specified and the
# target name ends with the suffix 'Private', the MODULE_INTERFACE_NAME value defaults to the
# non-suffixed target name, e.g.:
# For the SomeInternalModulePrivate target, the MODULE_INTERFACE_NAME will be
