Introduce a software-based page table walker for the arm64 MMU
emulation. This is foundational component for handling GVA-GPA
translations when a request missses the (future) software TLB.
For now, it handles only Page descriptors and does not yet support Block
descriptors or permission checks. These will be added in subsequent
patches.

Pound's asserts were broken from the very beginning and I've just
realized this. Fixing it is not my problem.

The term "memory" is really ambiguous in the context of an emulator,
especially since the MMU is being developed. It can refer to host memory, or
guest memory, or both.
