Allow to bind records with both primary constructor and properties via AsParameters

Is your feature request related to a problem? Please describe the problem.

I'm adding pagination support to my app. I want to avoid adding limit/offset parameters to every request, so I've added base record type PagedRequest:

public abstract record PagedReqeust
{
     public int? Limit { get; init; }
     public int? Offset { get; init; }
}

So I could use it like this:

public record MyRequest(string MyParam1, string MyParam2) : PagedRequest;

app
    .MapGet("/my-endpoint", ([AsParameters] MyRequest request) => { /* handle it */  });

Unfortunately, it doesn't work this way. Limit and Offset properties stay null even when query params provided.

Describe the solution you'd like

Would be nice if [AsParameters] taken properties into account when primary constructor is present.
