The architecture doesn't permit block descriptors at any arbitrary level of the page table walk; it depends on the granule size which levels are permitted. We implemented only a partial version of this check which assumes that block descriptors are valid at all levels except level 3, which meant that we wouldn't deliver the Translation fault for all cases of this sort of guest page table error. Implement the logic corresponding to the pseudocode AArch64.DecodeDescriptorType() and AArch64.BlockDescSupported().
