Fluent API: Timestamp/RowVersion

[bricelam]

We have a core-level convention for [Timestamp], but no corresponding IsRowVersion method.

In EF6, these were equivalent.

class Data
{
    [Timestamp]
    public byte[] Version { get; set; }
}

// Won't compile on EFCore
modelBuilder.Entity<Data>().Property(d => d.Version).IsRowVersion();
