Enable rs streaming and DB pinning for DuckLake

This is a manual backport of the PR duckdb#258 to `v1.3-ossivalis` stable
branch.

The support for direct attach, was recently added to DuckLake in
duckdb/ducklake#201. JDBC connection string example:

```
jdbc:duckdb:ducklake:postgres:postgresql://user:[email protected]:5432/lake1
```

This change enables `jdbc_stream_results` and `jdbc_pin_db` options
by default (unless they are specified by user) for DuckLake connections.

Testing: test coverage pending as DuckLake is not yet available in the
`main` barnch.
