Automatically import plugins in all applications with static Qt
Since all gui applications already need some QPA plugin added,
we might as well add the default plugin and generate the code
to import the plugins automatically.
User can opt out from the automation by removing relevant
items from CONFIG variable: link_qpa_plugin or import_plugins.
Task-number: QTBUG-28131
