13b2e741b9 arm64/mem: Add initial software page table walker 
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.

43bcf7e9a7 arm64/mem: Add MMU layer for GVA->GPA translation 
A new function, mmu_gva_to_gpa(), will be the sole entry point for
resolving guest virtual addresses. This initial implementation models
the processor's state on reset. The function inspects the M bit from the
emulated SCTLR_EL1 register. If the bit is clear, address mapping (GVA =
GPA) is performed. This is an architecturally-mandated behavior required
for the Arm guest to execute its initiall boot code before enabling
virtual memory.
