Prevent mapping to inaccessible construtors

[TimothyMakkison]

Stop CtorMapping from mapping to inaccessible constructors

Description
CtorMapping will try to construct an object from itself using inaccessible constructors. This usually occurs with records because they all have protected constructors.

[Mapper(UseDeepCloning = true)]
public static partial class Mapper
{
    public static partial MyRecord Map(MyRecord src);
    public static partial MyClass Map(MyClass src);
}
public class MyClass
{
    protected MyClass(MyClass myClass)
    {
    }
}
public record MyRecord
{
    public int Value { get; set; }
}

// Generates
public static partial global::Riok.Mapperly.Sample.MyRecord Map(global::Riok.Mapperly.Sample.MyRecord src)
{
    return new global::Riok.Mapperly.Sample.MyRecord(src); // invalid can't access constructor
}

public static partial global::Riok.Mapperly.Sample.MyClass Map(global::Riok.Mapperly.Sample.MyClass src)
{
    return new global::Riok.Mapperly.Sample.MyClass(src); // invalid can't access constructor
}

• Added accessibility check to CtorMapping
• Added unit test
