Enable authorization of materialized views

[kubikb]

resolves dbt-labs/dbt-adapters#773.

Problem

Similarly to BigQuery views, BigQuery materialized views can also be authorized to access the data in another dataset(s). However, providing the grant_access_to configuration to a model with materialized_view materialization goes silently ignored and the materialized view does NOT get authorized to access data in another dataset. With models with view materialization, the grant_access_to configuration leads to the desired behavior, namely the view gets authorized to access data in another dataset.

Solution

This pull request add logic to handle the config grant_access_to also for models with materialization materialized_view. The PR also extends currently existing tests.
