[DuckDB] Implement replacement scan function for Lance Scan in DuckDB

[eddyxu]

Problem Statement

DuckDB has a concept of replacement scan when the URL of dataset matches to certain pattern, the URL itself can be used to indicate which scan function to call,

For example,

SELECT * FROM s3://foo/bar/zoo.lance
-- Replace
SELECT * FROM lance_scan("s3://foo/bar/zoo.lance")

Reference of the old (c++) implementation

Desired Behavior

Re-enable the scan replacement of lance scan in the rust-based duckdb extension.
