Support HasData for List<X> type fields

[yinzara]

When using a List<string> type field, the mapping properly becomes a text[] type in PostgreSQL and works normally.
However we can't use UseData with an entity that has this mapping as we get the following exception:

The type mapping for 'List<string>' has not implemented code literal generation.

I would love it if the type mapping for List<string> supported code literal generation.

@yinzara you should be able to use an array (string[]) in HasData, have you tried that?

[yinzara]

Yes, that does work :-)
But List<X> does not.

I'm actually implementing this right now and have a PR to make it work.

Closing as this was done on the EF side (dotnet/efcore#28212).
