KVM: x86: Fold 'enum kvm_ex_reg' definitions into 'enum kvm_reg'
Now that indexing into arch.regs is either protected by WARN_ON_ONCE or done with hardcoded enums, combine all definitions for registers that are tracked by regs_avail and regs_dirty into 'enum kvm_reg'. Having a single enum type will simplify additional cleanup related to regs_avail and regs_dirty.
