ACRN 2.0 introduced Inter-VM communication feature by enabling the ivshmem v1.0 protocol/channel to communication
between VMs. To support the community's application Security Development Lifecycle (SDL), we provide a security hardening
guideline with some pointers to consider when using this channel by userspace application in case of additional security
requirments for Confidentiality, Integrity, or Authenticity.

Update the 'ivshmem' document to clarify the existence of two similar
mechanisms to expose this device to User VMs. One is implemented in the ACRN
Device Model and another (future) is implemented in the hypervisor.
