arm64/vmm: Set and use the fine-grained traps
Set the Fine-grained trap registers to trap any features we don't support. These are expected to be more useful when we support nested virtualisation, so for now just the base features and GICv3 are not trapped. As nested virtualisation will require VHE we only set the fine-grained trap registers when VHE is used. Sponsored by: Arm Ltd Differential Revision: https://reviews.freebsd.org/D54687
