/vsigs/: Add Google Cloud Run environment detection for GCE authentication (#13544)

When running GDAL in Google Cloud Run, the /vsigs/ virtual file system fails to automatically detect that it's running in a Google Cloud environment. This causes GDAL to skip the GCE metadata service for service account authentication, resulting in authentication failures when accessing Google Cloud Storage.

The issue occurs because Cloud Run containers don't have the DMI files (/sys/class/dmi/id/product_name) that GDAL checks to detect GCE instances on Linux. Users are forced to manually set CPL_MACHINE_IS_GCE=YES as a workaround in their Cloud Run deployments (e.g., Titiler).
Solution

Add detection for Google Cloud Run environments by checking for Cloud Run-specific environment variables:

    CLOUD_RUN_TIMEOUT_SECONDS (Cloud Run services)
    CLOUD_RUN_JOB (Cloud Run jobs)
    CLOUD_RUN_WORKER_POOL (Cloud Run worker pools)
