Prototype twister testing in LAVA

The goal is to use artifacts from Oniro zephyr builds with twister's --test-only option and let twister do all the heavy-lifting in terms of flashing all the images to the board and getting the results back to LAVA.

try doing it on the local host. Try with philosopher image or one of the zephyr kernel tests once the build for those is fixed if it's working, move this to lava. We can utilize LAVA docker job for this. The only unknown for me atm is how to parse the results from twister but imo shouldn't be too hard.
