KVM: arm64: implement dummy guest HVC handler at HYP

Prepare the hypervisor for relaying pKVM TRNG interface calls directly
to secure world, by introducing a hook for HVC calls issued from AArch64
state. The hook currently does nothing, so all HVCs intercepted in this
way will still cause an exit back to the host.
