Publish the AotCompatibility.TestApp project as part of PR validation (#5622)

- Remove AI in Microsoft.Extensions.AI.AotCompatibility.TestApp so it can be used for all projects
    - Analyze all libraries except the ones that have current warnings
- Publish the app from the AzDO pipeline
- Clean up the AotCompatibility.TestApp
    - Remove unnecessary code in Program.cs by turning off ReferenceTrimmer
    - Make the project publishable without passing in a TFM by only targeting a single TFM
- Fix part of Compliance.Redaction trimming issues by reenabling the Config Binder source generator.
