feat: add dremio__target_database dispatch macro

[devin-ai-integration]

Summary

Adds a dremio__target_database() dispatch macro so the elementary package can correctly resolve the target database when running against a Dremio adapter. Without this, the default dispatch (target.dbname) is used, which is Undefined for Dremio — Dremio profiles use database for the catalog/space name.

Review & Testing Checklist for Human

• Verify that target.database is the correct profile property for dbt-dremio (Dremio profiles define database as the catalog/space name)
• Confirm no other Dremio-specific dispatches are missing in cross_db_utils

Notes

• This is a companion change to elementary PR #2135 which adds Dremio (and other warehouse) CI support
• Requested by: @haritamar
• Link to Devin session

Summary by CodeRabbit

• New Features
  • Added support for Dremio as a target database option, enabling users to configure and utilize Dremio in their database workflows and operations.
