CMake: Fix directory scoping issue for qt6_generate_deploy_script

Consider a Qt target created in a subdirectory and a call to
qt6_generate_deploy_app_script(target) in the parent directory.

Once qt6_generate_deploy_script (called by
qt6_generate_deploy_app_script) is run, the target has already been
finalized. However, qt6_generate_deploy_script needs to run before
finalization, because:
- qt6_generate_deploy_script marks the target as to be deployed
- the finalizer generates plugins information only if the target was
  marked to be deployed

Fix this in qt6_generate_deploy_script by checking whether the target
was already finalized. In that case, generate the plugin deployment
information right away.

Pick-to: 6.5
