Add EventCounters to AotCompatibility.Test

[eerhardt]

This ensures that the OpenTelemetry.Instrumentation.EventCounters library stays AOT-compatible.

@eerhardt The AOT workflow does not always run. You would have to change the path here: https://github.com/open-telemetry/opentelemetry-dotnet-contrib/blob/main/.github/workflows/ci-aot.yml#L6-L8 and also just test the AOT compatibility outside of the workflow to ensure that EventCounters instrumentation is actually AOT-compliant.

(I can't push to your branch.)
@utpilla: thanks for reviewing! OpenTelemetry.Instrumentation.EventCounters is currently AOT-compliant. See: https://github.com/open-telemetry/opentelemetry-dotnet-contrib/actions/runs/5978918066/job/16221944116?pr=1324

LGTM assuming GitHub workflow file got updated. Thanks!

I've tested it locally, and it worked. Is there a way to manually kick off the CI leg on this change?

@Yun-Ting's Draft PR had these same changes, and the AOT leg passed on it: https://github.com/open-telemetry/opentelemetry-dotnet-contrib/actions/runs/5978918066/job/16221944116

@eerhardt You could add a simple workflow_dispatch event to the workflow and then you should be able to manually run the CI on your fork: https://docs.github.com/en/actions/using-workflows/manually-running-a-workflow.

Thanks for the help! I was able to successfully run the workflow in my fork:
