Add support for mapping inner class

Is your feature request related to a problem? Please describe. The internal class can correspond to properties declared as private set.

Describe the solution you’d like

record CarDto(string? Id);
partial class Car
{
    public string? Id { get; private set; }

    public void Update(CarDto dto)
    {
        Mapper1 mapper = new Mapper1();
        mapper.MergeCarDto(dto, this);
    }

    [Mapper(UseDeepCloning = true)]
    internal partial class Mapper1
    {
        public partial void MergeCarDto(CarDto source, Car target);
    }
}

Describe alternatives you’ve considered Currently using Automapper, but the performance is not optimal.

Additional context N.A.

Good find.

C# properties are two methods that mutate a private backing field ie <Id>k__BackingField. Mapperly is trying to map the two fields together. Not sure if this only happens with private set.

I’ll see if I can fix it later
