CMake: Pierce through LINK_ONLY deps in finalizer dep traversalv6.2.0-beta1

Ensure that the finalizer approach of
__qt_internal_propagate_object_library considers $<LINK_ONLY:>
libraries when traversing the dependencies of a target.

The issue was discovered when using the Quick.Shapes QML module in a
static build. The module has both a backing library and a plugin.
The backing library has some resource objects associated with it.
When the targets are exported, the plugin INTERFACE_LINK_LIBRARIES
has a $<LINK_ONLY:QuickShapes> dependency.

This ensures that the library will be linked, but depending on which
linking approach in __qt_internal_propagate_object_library is used,
the resources might not be linked to the final executable.

The resources are linked correctly when using the
target_link_libraries approach, but not when using the finalizer or
target_sources approach.

This change fixes the finalizer approach, but the target_sources
approach is still broken.
