Motivation
It's currently not possible to run on on MiG paritionned GPU as those have insufficient permission when using nvidia-smi cli to access available memory.
Tested on H100 & H200.
See #2933
Modifications
Added a
SGLANG_GPU_MEMORY_TOTAL_FALLBACKenvironment variable to manually set available memory when nvidia-smi is not possible
