Fix SAM2 benchmark script on cuda graph (#22377)

### Description
Update segment anything 2 benchmark script:
(1) Fix cuda graph in benchmark. Make sure --use_cuda_graph takes effect
and random_inputs() generates according to the dtype of the model.
(2) Add a parameter to enable profiling.
(3) Use latest cuda 12.6.2 and cudnn 9.5.
(4) Update README.md.

### Motivation and Context
Previous, --use_cuda_graph does not take effect. This fixes the
benchmark.
