  1. west: runners: Add west rtt command with pyocd implementation 

    This command runs separately from a debug server, instead of attaching
to a running server. This is both the easiest out of the box experience,
and also should be possible to implement consistently for most runners.

This commit includes an initial implementation for pyocd.

  2. west: runners: Implement the west rtt command for openocd 

    This was non-trivial, as openocd is a bit weird to work with. Using only
commands passed with '-c' arguments, I couldn't get it to reliably resume
(or just not halt) the target when started. I tried using the 'sleep'
command, and various 'configure -event XX { resume }' events, but nothing
panned out, as it seems to always halt after all `-c` commands have been
run.

To avoid that, this waits for the TCL RPC port to be up, and sends a
resume command there. This works reliably.

  3. west: runners: Implement the west rtt command for jlink 

    Moves the telnet client into runners/core.py as well, as this is now shared
between openocd and jlink.
