backends/host_iommu_device: Introduce HostIOMMUDeviceCaps
HostIOMMUDeviceCaps's elements map to the host IOMMU's capabilities.
Different platform IOMMU can support different elements.
Currently only two elements, type and aw_bits, type hints the host
platform IOMMU type, i.e., INTEL vtd, ARM smmu, etc; aw_bits hints
host IOMMU address width.
Introduce .get_cap() handler to check if HOST_IOMMU_DEVICE_CAP_XXX
is supported.
