Pull request overview

This PR introduces a comprehensive refactoring of the stepper motor overlay configuration and thread management infrastructure. The main purpose is to modernize the device configuration approach by migrating from Zephyr aliases to chosen nodes, introduce a base Thread class to reduce code duplication, and improve the stepper driver API usage. The changes also establish proper test infrastructure with fake stepper drivers, separating test concerns from the main application.

Key Changes

• Migrated device configuration from devicetree aliases and zephyr,user properties to chosen nodes (focuser,uart, focuser,stepper, focuser,stepper-drv)
• Introduced a base Thread class to eliminate duplication in thread creation logic between FocuserThread and UartThread
• Created dedicated test infrastructure using Zephyr's fake stepper drivers, removing qemu_cortex_m0 support from the main application
• Updated stepper driver API calls from stepper_enable/stepper_disable to stepper_drv_enable/stepper_drv_disable

• The comment is outdated. It mentions "swap in Zephyr's GPIO H-bridge stepper driver", but the test now uses the fake stepper driver (zephyr,fake-stepper-controller and zephyr,fake-stepper-driver) as configured in the overlay file, not the H-bridge driver. The comment should be updated to reflect the use of the fake stepper driver for testing.
