Allow to specify FieldInfo for a shadow property in Fluent API

We think this might mean that when a property is configured as a shadow property, it can later get a FieldInfo and become a field-backed non-shadow property.

We made the decision that during EF Core 3.0 we would re-enable configuration like this, after breaking it in preview 4. From the breaking change documentation:

Mitigations

Field-only properties must be named the same as the field they are mapped to. In a later preview of EF Core 3.0, we plan to re-enable explicitly configuring a field name that is different from the property name:

modelBuilder
   .Entity<Blog>()
   .Property("Id")
   .HasField("_id");

Unfortunately we ended up punting this past 3.0.

This issue is closed but this does not seem to be fixed. Is this a valid workaround?:

modelBuilder
   .Entity<Blog>()
   .Property("_id")
   .HasColumnName("Id");

@hisuwh The issue was fixed in 3.1.11, if you are still experiencing it in 5.0.0 or later please open a new issue.

The proposed workaround is correct.

I'm using 3.1.16 and am still experiencing this issue. I'm not in a position to move to 5.0.0 yet.
