The virt machine has properties to enable MTE and Nested Virtualization

supports it today only looks for KVM and bails out if it finds it.

Extend the checks to HVF as well as it does not support either today.

Without this check, what happens if you try to enable
both eg virtualization and hvf? Crash, unhelpful error
message, something else?

The guest just never gets either feature enabled. No crash, no error message.
