Give Partitioning Information from Ducklake

[J-Meyers]

Ducklake contains within it effective partitioning information (when the min and max values are equal for a column's data stats), duckdb has existing mechanisms for this to be reported to improve aggregation performance right now and hopefully join performance in the future. Ducklake should report this info so it can be taken advantage of.

Ducklake should not give worse performance than delta lake
