[snpe] Configure env var `ADSP_LIBRARY_PATH` at init #22

anyj0527 · 2025-08-26T05:06:15Z

Commit by @abhajaswal

Add functionality to read ADSP library path from configuration file or use default path.
The change includes a helper function to trim strings and a new function to set the ADSP_LIBRARY_PATH environment variable.
This ensures the SNPE backend can properly locate necessary libraries for hardware acceleration.
