[TimeSeries]: Enabled Multistage build (open-edge-platform#846)

enables multistage Docker builds for the Time Series Analytics microservice and updates string formatting to use parameterized logging throughout the codebase. The changes improve build efficiency, security, and logging consistency while adding Intel GPU support.

Key changes include:

Converting Docker build to use multistage approach with separate builder and runtime stages
Updating all string formatting in logging statements to use parameterized format strings with %s placeholders
Adding Intel GPU tools and drivers to the Docker image
