verification/dot2k: Simplify manual steps in monitor creation

This patch reduces and simplifies the manual steps still needed in
creating a new RV monitor.

It extends the dot2k script to create a tracepoint snippet and a
Kconfig file for the newly generated monitor. Those files can be kept
in the monitor's directory but shall be included in the main tracepoint
header and Kconfig.
Together with the checklist, dot2k now suggests the lines to add to
those files for inclusion and the Makefile line to compile the new
monitor:

 Writing the monitor into the directory monitor_name
 Almost done, checklist
   - Edit the monitor_name/monitor_name.c to add the instrumentation
   - Edit kernel/trace/rv/rv_trace.h:
 Add this line where other tracepoints are included and DA_MON_EVENTS_ID is defined:
 #include <monitors/monitor_name/monitor_name_trace.h>

   - Edit kernel/trace/rv/Makefile:
 Add this line where other monitors are included:
 obj-$(CONFIG_RV_MON_MONITOR_NAME) += monitors/monitor_name/monitor_name.o

   - Edit kernel/trace/rv/Kconfig:
 Add this line where other monitors are included:
 source "kernel/trace/rv/monitors/monitor_name/Kconfig"

   - Move monitor_name/ to the kernel's monitor directory (kernel/trace/rv/monitors)
