Feature: GroupBy aggregate value from owned entities

[Zetanova]

With efcore 5 it is not possible to create an aggregate from an owned entity.

Following throws an exception

[Owned]
public sealed class Stats
{
     public int Value1 { get; set; }
}

var query = context.Records
.GroupBy(n => n.Category)
.Select(g => new 
{
      Category = g.Key,
      Total: g.Sum(n => n.Stats.Value1) 
});

Same query and it works

var query = context.Records
.Select(n => new 
{
      n.Category,
      n.Stats.Value1
})
.GroupBy(n => n.Category)
.Select(g => new 
{
      Category = g.Key,
      Total: g.Sum(n => n.Value1) 
});
