This PR fixes the handling of drop_chunks when the hypertable's time field is a TIMESTAMP or DATE field. Previously, such hypertables needed drop_chunks to be given a timestamptz in UTC. Now, drop_chunks can take a DATE or TIMESTAMP. Also, the INTERVAL version of drop_chunks correctly handles these cases. A consequence of this change is that drop_chunks cannot be called on multiple tables (with table_name = NULL or schema_name = NULL) if the tables have different time column types.
