Add Support For FastEndpoints

[KyleMcMaster]

We already have support for Minimal API results so it would be awesome to see what work is needed to also support FastEndpoints like we do for Controllers/APIEndpoints. If any code is needed it could probably be added to the AspNetCore package unless we would like to add an Ardalis.Result.FastEndpoints package

FastEndpoint already has a SendResultAsync() to send any IResult instance produced by the Results static class in Minimal APIs. So simply you can call something like this:
await SendResultAsync(result.ToMinimalApiResult());
