Add OwnershipAssignment to dbt VirtualView

[usefulalgorithm]

🤔 Why?

Enables assigning ownership to dbt model's virtual views, or both the virtual view and the dataset itself.

Tracked by SC20587

🤓 What?

• Added a config field for meta_ownerships:

meta_ownerships:
  - meta_key: owner
    ownership_type: Data Steward
    assignment_target: materialized_table # assigns the owner to either "materialized_table" (the dataset), "dbt_model" (the virtual view), or "both". Default is the materialized table.

• Added support for parsing string values in dbt model's meta field, such that a string value containing commas will be parsed as a sequence of string values

🧪 Tested?

Tested with the newly added config, the ownership information was added correctly.

Let's also add a config to control the desired behavior, i.e., assigning owners to dbt model, materialized tables, or both.
