Create dashboards and visualizations with code

[angorayc]

Describe the feature:
This issue provides the expected functionalities from threat hunting and GenAI team upon dashboard as code feature:

Expected functionalities: Dashboard Creation API

Create dashboards with code

1. Space Selection: Allow users to specify the space where the dashboard will be created.
2. Managed Dashboard Option: Enable users to define whether the dashboard is a managed dashboard.
3. Tag Assignment: Let users assign a tag to the dashboard. If the specified tag does not exist, the API should automatically create it.
4. Time Storage: Provide an option for users to specify whether to store time with the dashboard, along with the ability to input a time range.
5. Query Integration: Accept a dashboard query in either kql or ES | QL format.
6. Control Bar Configuration: Allow users to enable a control bar for the dashboard and supply the necessary configuration for it.
7. Supports ad hoc dataview
8. Supports Add visualization to dashboard

Create visualizations with code

1. Space Selection: Allow users to specify the space where the visualization will be created.
2. Managed Dashboard Option: Enable users to define whether the visualization is a managed dashboard.
3. Tag Assignment: Let users assign a tag to the dashboard. If the specified tag does not exist, the API should automatically create it.
4. Time Storage: Provide an option for users to specify whether to store time with the dashboard, along with the ability to input a time range.
5. Query Integration: Accept a dashboard query in either kql or ES | QL format.
6. Supports ad hoc dataview
7. Generate Lens attributes with code - @kbn/lens-embeddable-utils, src/platform/packages/shared/kbn-lens-embeddable-utils/attribute_builder/lens_attributes_builder.ts

Use cases:

Create dashboards with code

Given a bunch (e.g. 1000+) of ES|QL queries, we would like to turn them into Kibana dashboards.

Create visualizations with code

• We are currently maintaining lots of lens attributes in the code in order to render them with Lens Embeddable: https://github.com/elastic/kibana/blob/da25d13a2ac5be97216e202bf5d6bda6ff920b3b/x-pack/solutions/security/plugins/security_solution/public/common/components/visualization_actions/lens_attributes/users/kpi_total_users_area.ts

• We use Kibana UI to generate the attributes and export them: https://github.com/elastic/kibana/tree/da25d13a2ac5be97216e202bf5d6bda6ff920b3b/x-pack/solutions/security/plugins/security_solution/public/common/components/visualization_actions/lens_attributes
  But these attributes are not ideal to be maintain in the github. Is there an easier way to generate these attributes and create visualization with the api, so we don't need to maintain them in the github?
