Resolve #8298

Now we can use IRemoteStreamContent to handle files just like IFromFile.

Configure<AbpAspNetCoreMvcOptions>(options =>
{
    options.ConventionalControllers.FormBodyBindingIgnoredTypes.Add(typeof(CreateFileInput));
    options.ConventionalControllers.FormBodyBindingIgnoredTypes.Add(typeof(CreateMultipleFileInput));
});

public class CreateFileInput
{
    public string Name { get; set; }

    public IRemoteStreamContent Content { get; set; }
}

 public class CreateMultipleFileInput
{
    public string Name { get; set; }

    public IEnumerable<IRemoteStreamContent> Contents { get; set; }

    public CreateFileInput Inner { get; set; }
}
