Query: Disallow tracking queries for owned entites without their owners

[smitpatel]

Resolves #13036

[AndriySvyryd]

The defining entity isn't always the owner. We shouldn't prevent weak entities to be tracked.

I guess it been a while we all had discussion about weak vs owned.
Filed #16999 to discuss when you are back at work.

This PR breaks completely scenarios when an entity inherits an owned entity from its base class:

[Owned]
public class OwnedEntity
{
	public string Prop { get; set; }
}

public class A 
{
	public string Foo { get; set; }
}

public class B : A
{
	public string Bar { get; set; }
}

// ...

builder
	.OwnsOne(a => a.AuditLog); //<-- works only for base type

// ...

await dbContext.Set<B>().SingleOrDefaultAsync(e => e.Bar == bar); //<-- throws InvalidOperationException
