Fixes https://github.com/duckdblabs/duckdb-internal/issues/1217, duckdb/duckdb#10495
This PR should make a better attempt at implementing https://peps.python.org/pep-0249/#type-objects-and-constructors
We add the required type object sentinels:
STRINGNUMBERDATETIMEBINARYROWID(None, as DuckDB doesn't have a way to detect this on a LogicalType)The objects returned for the
type_codeof thedescriptionis aDuckDBPyType.The sentinels are of type
DBAPITypeObjectand are overloaded to be compared with theDuckDBPyTypeobjects.The constructors listed by the PEP are not added, they could be added in the future.
