KVM: arm64: Don't advertise unsupported features for protected guests

Both SVE and PMUv3 are treated as "restricted" features for protected
guests and attempts to access their corresponding architectural state
from a protected guest result in an undefined exception being injected
by the hypervisor.

Since these exceptions are unexpected and typically fatal for the guest,
don't advertise these features for protected guests.
