Add LASTWITHTIME to FunctionRegistry

LASTWITHTIME queries from a Trino connector fail with

`Unexpected aggregate expression: 'lastwithtime(id,timestamp,'string')'`

When further inspected the logs show:
`

LASTWITHTIME is not included in the above list and therefore cannot be used in the queries

Start at the FunctionRegistry entry point and inspect how the existing aggregate functions are registered. Add LASTWITHTIME consistently with those registrations, then verify that the reported Trino query no longer fails with an unexpected aggregate expression and that the function appears in the registry.
