Alexandru Croitor b3b1e47378 CMake: Introduce qt_internal_add_app
This new function is meant to be used where load(qt_app) is used.

It delegates functionality to qt_add_executable, while handling
some additional behavior via a finalization function (mostly handling
of macOS Info.plist files and icons, as well as Windows icons and
resource files)

It uses a new PlatformAppInternal interface target.

Task-number: QTBUG-85757
