67 re working arm64 vt code base

This is an exceptional merge with a major rework of the AVZ hypervisor and capsule (ex-ME) management.
It still needs some consequent changes but the current SO3 environment is not concerned so far.
I know there is still a minor issue with the vuart frontend/backend when dealing with several capsules at the same time.
