target/riscv: add Zicbop cbo.prefetch{i, r, m} placeholder
The cmo.prefetch instructions are nops for QEMU (no emulation of the
memory hierarchy, no illegal instructions, no permission faults, no
traps).
Add a comment noting where they would be decoded in case cbo.prefetch
instructions become relevant in the future.
