ANDROID: KVM: arm64: iommu: Add new ops iotlb_sync_map()

Some IOMMU drivers might want to implement the iommu_ops
iotlb_sync_map() in the hypervisor. Add a new hypercall
and a hypervisor ops for that.

Changes from porting forward from 6.6 to 6.12:

- Export a wrapper around the hypercall so that the wrapper is treated
  as part of the ABI instead of the actual hypercall.
