By default, EGLInitialize() (in containers like Docker/Singularity or natively) looks to bind to GPU:0 (first absolute device) on a given machine.
When running MatterSim under HPC (e.g., via SLURM or other job schedulers) that allocate GPU != 0, EGLInitialize fails.
This PR addresses this by looping through all devices visible to current allocated job (SLURM task), and initializing appropriately. No change in the underlying Dockerfile/build process is necessary (eglext.h is included by default).
