hypervisors: Confidential Guests do not support Device hotplug

Browse Source 
Similarly to VCPUs hotplug, Confidential Guests also do not support
Device hotplug.

Let's make it clear in the documentation and guard the code on both QEMU
and Cloud Hypervisor side to ensure we don't advertise Device hotplug as
being supported when running Confidential Guests.
