Fix linking of examples

Provide add_qt_gui_executable() as function in our public API that takes
care of automaticWinMain linkage. We can use this in the future to
encapsulate similarplatform-specific behavior and adjustments, such as
module generation onAndroid.

In order for the examples to see the function in Qt5CoreMacros, three more
additional fixes were required:

    * Do the build_repo_end() call _before_ attempting to build the
      examples, as we need the build_repo_end() to include QtPostProcess
      and complete the creation of all the target config files.
      Otherwise the find_package() calls in the examples see something
      incomplete.

    * Add more QT_NO_CREATE_TARGET guards

    * Always call find_dependency on the dependencies, regardless of the
      target creation mode. This way a find_package(Qt5 COMPONENTS
      Widgets) will still load Qt5CoreMacros.
