KVM: arm64: Add save/restore support for FPMR
Just like the rest of the FP/SIMD state, FPMR needs to be context
switched.
The only interesting thing here is that we need to treat the pKVM
part a bit differently, as the host FP state is never written back
to the vcpu thread, but instead stored locally and eagerly restored.
