Description

As part of dotnet/aspire#4684 to get the tracing for HTTP requests we need to enable the HttpActivityPropagationSupport MSBuild property.

If we do this manually, it works, so that's an easy workaround. But in an effort to reduce the manual effort people need to do to get .NET MAUI + .NET Aspire work, can we enable this property by default?

I guess this would be alike #9928 so we enable it only when the value is empty (aka not set by the project already) and its a non-Release build
