IL3000 error in MsQuicApi..cctor when publishing AOT

[euju-ms]

Describe the bug

When publishing an app that uses HttpClient, it results in IL3000.

System.Net.Quic.MsQuicApi..cctor(): 'System.Reflection.Assembly.Location.get' always returns an empty string for assemblies embedded in a single-file app. If the path to the app directory is needed, consider calling 'System.AppContext.BaseDirectory'.

To Reproduce

Here's a repo that contains the minimal repro console app: https://github.com/euju-ms/MsQuicApiError

1. Download the source code then open MsQuicApiError.sln from VisualStudio
2. Publish the project MsQuicApiError using Properties\PublishProfiles\FolderProflie.pubxml, then observe the error.

By the way, if I change the TargetPlatform to net9.0 then publish, then the publish succeeds.
