Trino support

[damian3031]

I would be awesome if we could add Trino support to dbt-date.

Currently, we maintain a separate package called dbt-trino-utils containing Trino-specific macro implementations.
However, as this package continues to grow with new additions, it introduces certain challenges.
Some of these packages have different dbt-core version requirements, which force us to use a lower version
for one of the packages.

It would be more efficient to directly add Trino implementations for a few macros into dbt-date
rather than replicating the entire test suite on our side.

Furthermore, this approach offers a more user-friendly experience as users won't need to install an additional package and make extra configurations in their dbt_project.yml file.

Regarding testing, we can set up a Docker container with a Trino image in CI and run tests on it.
