Add support for multiple connections (e.g. UART) from one device, enabling communication with second core UARTs. Feature implemented by extracting connection logic from DeviceAdapter to new DeviceConnection class with specialized implementations: - SerialConnection for hardware UART ports - ProcessConnection for native simulation - FifoConnection for QEMU communication Each connection maintains separate log files (handler.log, handler_1.log, etc.) and can be accessed via connection_index parameter in device methods like readline() and write(). This enables testing multi-core applications where different cores communicate through separate UART interfaces. Signed-off-by: Grzegorz Chwierut <grzegorz.chwierut@nordicsemi.no>

The Zephyr Project is a scalable real-time operating system (RTOS) supporting
multiple hardware architectures, optimized for resource constrained devices,
and built with security in mind.
The Zephyr OS is based on a small-footprint kernel designed for use on
resource-constrained systems: from simple embedded environmental sensors and
LED wearables to sophisticated smart watches and IoT wireless gateways.
The Zephyr kernel supports multiple architectures, including ARM (Cortex-A,
Cortex-R, Cortex-M), Intel x86, ARC, Tensilica Xtensa, and RISC-V,
SPARC, MIPS, and a large number of `supported boards`_.
