[Feature] Generate IEntityTypeConfiguration<T> Mappers

Currently all the mapping of the EntityTypes are generated in the function: protected override void OnModelCreating(ModelBuilder modelBuilder). This can become pretty large… I suggest we create scaffold a IEntityTypeConfiguration file for each entity and use these in the OnModelCreating function.

For example: Customer.cs

CustomerConfiguration.cs

internal class CustomerConfiguration : IEntityTypeConfiguration<Customer>
{
  public void Configure(EntityTypeBuilder<Customer> builder)
  {
     builder.HasKey(c => c.AlternateKey);
     builder.Property(c => c.Name).HasMaxLength(200);
     // ...
   }
}

DbContext

// OnModelCreating
builder.ApplyConfiguration(new CustomerConfiguration());

Optional:

• Choose a template name suffix

Will implement using https://github.com/lauxjpn/DbContextOnModelCreatingSplitter - initially just a checkbox to enable this!
