inspector: implement --cpu-prof[-path]
This patch introduces a CLI flag --cpu-prof that starts the V8
CPU profiler on start up, and ends the profiler then writes the
CPU profile before the Node.js instance (on the main thread or
the worker thread) exits. By default the profile is written to
`${cwd}/CPU.${yyyymmdd}.${hhmmss}.${pid}.${tid}.${seq}.cpuprofile`.
The patch also introduces a --cpu-prof-path flag for the user
to specify the path the profile will be written to.
