app-versions-9.0: Add more CHERI-RISC-V changes.

- Add a section on mode-dependent jumps.

- Add a note about reserved encodings for memory versioning and
  CRelocate.

- Add notes for C[GS]etHigh and CGetTop.

 \item \DDC{} and \PCC{} no longer relocate legacy memory accesses.
   These registers still constrain legacy memory accesses.  This
