Add Tags to Semantic Layer Saved Queries

[theyostalservice]

Title says it all.

This is modeled off of this previous PR adding features to Semantic Layer objects.

Linked PRs:

• the starting point at dbt-semantic-interfaces
• dbt-core
• schemas.dbt.com

Example of how this would look in an actual saved
query in a yml file:

saved_queries:
- name: with_list_tags_v2
    tags: ['tag_b', 'tag_d', 'tag_a']
    description: New customer orders by name and time
    query_params:
      metrics:
        - orders
      group_by:
        - Dimension('customer__customer_name')
        - TimeDimension('metric_time', 'day')
      where:
        - "{{ Dimension('customer__customer_type') }}  = 'new'"
    exports:
      - name: new_customer_orders_table
        config:
          export_as: table
      - name: new_customer_orders_view
        config:
          export_as: view
          alias: new_customer_orders_export_alias
          testing: "what"
          breaking: 'break it now'

If there's any testing I should do for this, please lmk. :-)
