embedded runner in lingo

[gundralaa]

I'm running into issues running multiple LF program regression tests on hardware.
Doing this by hand and collecting the results is quite tedious.
It would be nice for lingo run to utilize a probe-rs backend to allow for this automation for binaries meant for embedded devices.

@gundralaa do you want to tackle this?

This is a blank slate still, because there are no abstraction yet for runners.
