RISC-V: KVM: Add new exit statstics for redirected traps
Currently, kvm doesn't delegate the few traps such as misaligned
load/store, illegal instruction and load/store access faults because it
is not expected to occur in the guest very frequently. Thus, kvm gets a
chance to act upon it or collect statistics about it before redirecting
the traps to the guest.
Collect both guest and host visible statistics during the traps.
Enable them so that both guest and host can collect the stats about
them if required.
