[Feature Request] API to get list of graph optimizer names for a provider

### Describe the feature request

ONNX Runtime currently allow disabling some optimizers in session:
onnxruntime.InferenceSession(onnx_model_path, sess_options, providers=["CPUExecutionProvider"], **disabled_optimizers=[]**)

However, I do not know what optimizers are available in the installed onnxruntime package for current provider.

Shall we add an API to get list of optimizers for a provider?

### Describe scenario use case

I want to run only a set of optimizers and disable all other optimizers.
