iommu/vt-d: Add trace events for cache tag interface

Add trace events for cache tag assign/unassign/flush operations and trace
the events in the interfaces. These trace events will improve debugging
capabilities by providing detailed information about cache tag activity.
A sample of the traced messages looks like below [messages have been
stripped and wrapped to make the line short].
