KVM: arm64: Reduce the size of the vcpu flag members

Now that we can detect flags overflowing their container, reduce
the size of all flag set members in the vcpu struct, turning them
into 8bit quantities.

Even with the FP state enum occupying 32bit, the whole of the state
that was represented by flags is smaller by one byte. Profit!
