Alexandru Croitor 121f7f382b CMake: Allow installation of example sources into the Qt prefix 
In Qt 5 times, if Qt was configured with -make examples, running
make install would not only build and install the example binaries,
but would also install the example sources into the prefix.
Installation of example sources was not implemented when the Qt 6
build system has switched to using CMake.

There is still a use case for it though, mainly for Qt Creator, which
only shows the examples of a Qt kit if the sources are available.

In contrast to Qt 5, in Qt 6 we will not install example sources
by default. It will be opt in.

To enable installation of examples sources, configure with

 configure -make examples -install-examples-sources

or

 cmake -DQT_BUILD_EXAMPLES=ON -DQT_INSTALL_EXAMPLES_SOURCES=ON

The -make examples part is required, otherwise
-install-examples-sources has no effect.

All example sources can be installed by calling
 cmake --install . --component examples_sources
in the qt repo build directory.

In a top-level build, per-repo installation can be done using
 cmake --install . --component examples_sources_<repo_name>
where repo_name could be 'qtbase'.

A single example's source can be installed by calling
 cmake --install . --component examples_sources_<subdir_name>
where subdir_name is the subdirectory name of the example, e.g.
'gallery'.

Implement installation of example sources by hooking into the
qt_internal_add_example command.
This means that all examples in all repos need to be added via
qt_internal_add_example instead of add_subdirectory, to ensure the
sources are installed. The majority of repos already use it.

For testing purposes one can configure with
-DQT_BUILD_EXAMPLES=ON -DQT_INSTALL_EXAMPLES_SOURCES=ON
-DQT_INTERNAL_NO_CONFIGURE_EXAMPLES=ON to allow testing installation
of examples sources without building them.

Take into account an additional variable called
QT_INTERNAL_EXAMPLES_SOURCES_INSTALL_PREFIX to allow installation of
example sources into a location different from the example binaries.

As a cleanup, the NAME option that could previously be passed to
qt_internal_add_example_external_project has been removed.
That's because it's never used anywhere and could not have worked
anyway because qt_internal_add_example_in_tree never handled it.

Pick-to: 6.6
