Devicetree DTS alias support (#483)

* **New Features**
  * Phandle support for device-to-device property references.
  * Recognition of #define-style declarations in device trees.
  * Device nodes may include optional aliases alongside node names.

* **Improvements**
  * Flatter, consistent device hierarchy processing for generation.
  * Error and log messages now reference node names for clearer diagnostics.

* **Other**
  * Added a static ESP32-based device tree and minor DTS comment updates.
