iommu/vt-d: Introduce batched cache invalidation
Converts IOTLB and Dev-IOTLB invalidation to a batched model. Cache tag
invalidation requests for a domain are now accumulated in a qi_batch
structure before being flushed in bulk. It replaces the previous per-
request qi_flush approach with a more efficient batching mechanism.
