hypervisor: haxm: replace MemoryMapping with raw ptrs

The haxm vcpu code abused MemoryMapping to hold what is effectively a
raw pointer, not something created by mmap()/MapViewOfFile().

Additionally, the MemoryMapping was converted into a pointer and then
into a Rust &ref, which is inappropriate for memory that can be aliased
by the hypervisor.

Use raw pointers instead of unsoundly casting into a reference and add
unsafe blocks as appropriate.

crosvm - The Chrome OS Virtual Machine Monitor

crosvm is a virtual machine monitor (VMM) based on Linux’s KVM hypervisor, with a focus on simplicity, security, and speed. crosvm is intended to run Linux guests, originally as a security boundary for running native applications on the Chrome OS platform. Compared to QEMU, crosvm doesn’t emulate architectures or real hardware, instead concentrating on paravirtualized devices, such as the virtio standard.

crosvm is currently used to run Linux/Android guests on Chrome OS devices.
