arm: implement kdb watchpoint functions
Implement wrappers around the existing debug_monitor interface, to be
consumed by MI kernel debugger code.
For now, the various db_printf() calls in this code remain. In the
future, they could be converted to printf() or removed altogether, to
properly decouple the DDB and GDB options.
