west: add NXP S32 Debug Probe runner

The NXP S32 Debug Probe is a JTAG-based probe that enables debugging on
NXP S32 devices. This probe is designed to work in conjunction with NXP
S32 Design Studio and this runner offers a wrapper to launch a debug
session from cli.

`flash` command is not implemented at the moment because presently there
are no zephyr boards that can make use of it and test it.
