Add support for (yet again) more RVA23U64 missing extensions. Add
support for Zcmop, Zca, Zcf, Zcd and Zcb extensions isa string parsing,
hwprobe and kvm support. Zce, Zcmt and Zcmp extensions have been left
out since they target microcontrollers/embedded CPUs and are not needed
by RVA23U64

This series is based on the Zimop one [1].
