Implement also_requires to enforce view-database for execute-sql

Adds Action.also_requires field to specify dependencies between permissions.
When an action has also_requires set, users must have permission for BOTH
the main action AND the required action on a resource.

Applies this to execute-sql, which now requires view-database permission.
This prevents the illogical scenario where users can execute SQL on a
database they cannot view.

Changes:
- Add also_requires field to Action dataclass in datasette/permissions.py
- Update execute-sql action with also_requires="view-database"
- Implement also_requires handling in build_allowed_resources_sql()
- Implement also_requires handling in AllowedResourcesView endpoint
- Add test verifying execute-sql requires view-database permission

Fixes #2527
