Pytest Tests in Twister
summary
Adds a pytest executor plugin to Twister that actually runs pytest subprocesses, flashes or connects to targets, and returns results as junit XML so Twister parses them like other tests. Implements a device adapter abstraction so the same device-type agnostic tests run on hardware, QEMU or native POSIX. Ships fixtures for shell I/O, an MCU-based bootloader downgrade check using MCU manager, and a full LwM2M end‑to‑end interop case using a Docker server; the integration is working but adoption and multi-image/multi-device reuse remain limited.
