Merged PR 2580: Guest Payments metrics per customer segmentation

# Description

Modifies `int_core__mtd_guest_payments_metrics` to include the customer segmentation based on listings. `schema.yaml` is also affected including new fields, tests and apply the proper naming (from guest revenue to guest payments). I also modified a silly naming that was referring to deals to refer to listings/accommodations, my bad.
Added the macro to retrieve the production dimension in `int_core__mtd_vs_previous_year_metrics` to avoid propagating this upwards and messing up with the data display.

Overall, follows a similar strategy as we did for Booking, Guest Journey, Deal and Accommodation metrics. For reference, [here's the previous PR on Accommodations](https://guardhog.visualstudio.com/Data/_git/data-dwh-dbt-project/pullrequest/2575?_a=overview).
