Convert dynamic includes to static imports

When task/role files are included using include_tasks, tags are not
passed to the included tasks. As a result, tags like swift-config
do not have the intended effect. This patch changes include_tasks
to import_tasks for all cases where dynamic vars or loops are not used
so that tags are properly handled.
