We want to be able to run 64-bit ARM kernels using a 32-bit version of
crosvm, to make it more consistent use a u64 to represent
GuestAddress.

Add a module for accessing guest memory.
This module will replace all the slices that are used to access it
currently as those slices aren't valid because the memory is volatile
and a volatile slice doesn't exist in rust.
Modify the existing users so they no longer depend on the deprecated slice
access.
