Add historic and castle_type tags

[nvkelso]

Tell me more about this request?

Usually we'd insert something like castle_type into kind_detail instead of adding a new key.

Historic seems pretty wide, we'd probably want to map the values to new kinds?

We have created a style similar to OpenTopoMap which also shows palaces, for example this one: https://www.openstreetmap.org/way/38975518 and we didn't have any possibility to filter these buildings because we cannot find these data into vector-datasource. We don't know how to add this correctly into vector-datasource so we tried this. How can I add this properly into vector-datasource?
