CMake: Make qt_internal_walk_libs available in public projects
Needed for the upcoming static plugin mechanism, where we have to extract the list of Qt module dependencies of a target and then extract the plugins associated with those modules. To do that we need to recursively collect the dependencies of a given target. Rename the moved functions to contain the __qt_internal prefix. Also rename the existing QtPublicTargetsHelpers.cmake into QtPlatformTargetHelpers.cmake to avoid confusion with the newly introduced QtPublicTargetHelpers.cmake. Task-number: QTBUG-92933 Change-Id: I48b5b6a8718a3424f59ca60f11fc9e97a809765d Reviewed-by: Joerg Bornemann <joerg.bornemann@qt.io>
