Bind utility functions for date, timestamp, and interval types for C API

[mewim]

In #1471 the basic date, timestamp and interval types are binded for C API. However, the user has to manually translate the values from/to the corresponding C struct to work with these data types. We should bind more utility functions defined in https://github.com/kuzudb/kuzu/blob/master/src/include/common/types/date_t.h, https://github.com/kuzudb/kuzu/blob/master/src/include/common/types/interval_t.h, and https://github.com/kuzudb/kuzu/blob/master/src/include/common/types/timestamp_t.h to improve the usability.
