Included columns inside owned entities (HasIndex, IncludeProperties)

## File a bug

Properties inside owned types cannot be included columns in an index.
Additionally there might be an issue with including the a property with the same name on two different owned entities.

### Include your code

To fix any bug we must first reproduce it. To make this possible, please attach a small, runnable project or post a small, runnable code listing that reproduces what you are seeing.

It is often impossible for us to reproduce a bug when working with only code snippets since we have to guess at the missing code.

Use triple-tick code fences for any posted code. For example:

```C#
using Microsoft.EntityFrameworkCore;

using var context = new MyDbContext();

await context.Database.EnsureDeletedAsync();
await context.Database.EnsureCreatedAsync();

public class MyDbContext : DbContext
{
public DbSet People { get; set; } = default!;

protected override void OnModelCreating(ModelBuilder modelBuilder)
{
base.OnModelCreating(modelBuilder);

modelBuilder.Entity()
.HasIndex(f => f.SocialInsuranceNumber)
.IncludeProperties(
f => new
{
f.HomeAddress.StreetNumber,
// If a second property is added, it has to be named differently to avoid CS0833
//Work = f.WorkAddress.StreetNumber,
});
}

protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
=> optionsBuilder
//.UseSqlServer(FiddleHelper.GetConnectionStringSqlServer()).LogTo(Console.WriteLine);
.UseSqlServer($@"Server=(localdb)\mssqllocaldb;Database={GetType().Assembly.GetName().Name};Trusted_Connection=True").LogTo(Console.WriteLine);
}

public class Person
{
public Guid Id { get; set; }
public int SocialInsuranceNumber { get; set; }
public StreetAddress HomeAddress { get; set; }
public StreetAddress WorkAddress { get; set; }
}

[Owned]
public class StreetAddress
{
public int StreetNumber { get; set; }
}
```

### Include stack traces

Include the full exception message and stack trace for any exception you encounter.

Use triple-tick fences for stack traces. For example:

```
System.ArgumentException
HResult=0x80070057
Message=The expression 'f => new <>f__AnonymousType0`1(StreetNumber = f.HomeAddress.StreetNumber)' is not a valid member access expression. The expression should represent a simple property or field access: 't => t.MyProperty'. When specifying multiple properties or fields, use an anonymous type: 't => new { t.MyProperty, t.MyField }'. (Parameter 'memberAccessExpression')
Source=Microsoft.EntityFrameworkCore
