Description
### Describe the feature request
In python, shrinking memory on each run is supported as following.
ro2 = onnxrt.RunOptions()
ro2.add_run_config_entry("memory.enable_memory_arena_shrinkage", "cpu:0;gpu:0")
I have tested and it works fine. I would like to use this in c# as well.
If the features are not in a job queue yet, any suggestion how I can start exposing this to c# and build myself
before the official release?
### Describe scenario use case
My case is that I have many models that infers at the same time, in order to analyze the whole database.
(OCR, Classifcation, Object Detection.. etc)
Due to gpu memory shortage, I would like the session to shrink the gpu memory on each run.

Research direction
Start with the Python RunOptions example and the memory.enable_memory_arena_shrinkage configuration key, then trace how RunOptions is exposed through the C# API. Check the existing C# binding and its tests, if present; done means C# users can configure equivalent CPU and GPU arena shrinking for each run.
