Merged PR 3187: Move deal lifecycle related models to cross

# Description

Moves from intermediate/core to intermediate/cross the following models:
- `int_core__mtd_deal_lifecycle`
- `int_core__mtd_deal_metrics`

to their equivalents:
- `int_mtd_deal_lifecycle`
- `int_mtd_deal_metrics`

This also changes the schema entries, from core to cross, including changing the name of the model in the entry.
This also changes the dependencies, namely in `int_mtd_deal_metrics`, `int_mtd_vs_previous_year_metrics` and `int_monthly_aggregated_metrics_history_by_deal`.
This does NOT aim to alter the logic of the lifecycle in any case; it will be done in a separated PR.

Runs correctly end-to-end. We might need to drop the old models from production manually.

# Checklist

- [X] The edited models and dependants run properly with production data.
- [X] The edited models are sufficiently documented.
- [X] The edited models contain PK tests, and I've ran and passed them.
- [X] I have checked for DRY opportunities with other models and docs.
- [X] I've picked the right materialization for the affected models.
