Add C# and Python language bindings for GetCompatibilityInfoFromModel / GetCompatibilityInfoFromModelBytes (#27565)
### Description
<!-- Describe your changes. -->
This change adds C# and Python language bindings and tests for the
recently-introduced GetCompatibilityInfoFromModel /
GetCompatibilityInfoFromModelBytes API.
### Motivation and Context
<!-- - Why is this change required? What problem does it solve?
- If it fixes an open issue, please link to the issue here. -->
#27015 introduced a new API to facilitate getting the model
compatibility information from the metadata of a model (either a file or
the model bytes). For convenience, we should ideally have some other
language bindings included to make consumption a little easier.
