Adds a new entry VTDPASIDCacheEntry in VTDAddressSpace to cache the pasid entry and track PASID usage and future PASID tagged DMA address translation support in vIOMMU. When guest triggers pasid cache invalidation, QEMU will capture it and update or invalidate pasid cache. vIOMMU emulator could figure out the reason by fetching latest guest pasid entry in memory and compare it with cached PASID entry if it's valid.
