IntelliCode C# Dev Kit: Starred completions for class members don't work on MacOS

[vivlimmsft]

Starred member completions (e.g. stars in the completion list after typing myObject.) don't work on MacOS. (observed on arm64, but I believe this extends to x64 as well)
(note: Starred argument completions (e.g. stars in the completion list after typing myObject.myMethod( are unimpacted because they work totally differently and don't depend on any native libraries.)

On the currently released version 2.0, the process that hosts onnxruntime and blingfire fails silently. In the upcoming 2.1 this is improved with output window logging.
Neither of these can be loaded:

'.../libonnxruntime.dylib' not valid for use in process: mapped file has no Team ID and is not a platform binary (signed with custom identity or adhoc?)
'.../libblingfiretokdll.dylib' not valid for use in process: mapped file has no Team ID and is not a platform binary (signed with custom identity or adhoc?

The first one is resolved after an update to 1.17.3, suggesting that microsoft/onnxruntime#16168 can be resolved. The latter we'll need to fix since we build it ourselves.
