cloudsecuritycompliace: replace organization with parent to support PLE

[modular-magician]

Description

This PR introduces Project Level Enablement (PLE) support for Cloud Security Compliance resources. Previously, these resources were strictly bound to the organization level. This change allows users to create and manage controls, frameworks, and deployments at the project level as well.

Key Changes:

• Introduced parent: Replaced the hardcoded organization parameter with a flexible parent parameter across CloudControl, Framework, and FrameworkDeployment.
• Backward Compatibility: The organization field is now marked as deprecated, but old configurations remain fully supported.
  • Added exactly_one_of: [parent, organization] with both fields marked as optional: true to allow seamless migration.
  • Added a pre_create custom code hook (cloudsecuritycompliance_set_parent.go.tmpl) to automatically construct the parent string for users who only provide organization.
  • Preserved the Terraform Identity Schema by keeping the legacy organizations/{{%organization}}/... format as the first entry in import_format, ensuring no state corruption for existing users.
• Perpetual Diff Fix: Added diff_suppress_func: 'tpgresource.CompareResourceNames' to targetResourceConfig.existingTargetResource in FrameworkDeployment.yaml to prevent state drift when the API normalizes between project IDs and project numbers.
• Expanded Testing: Added comprehensive Terraform acceptance tests demonstrating project-level configurations, folder-level deployments, and targeting specific applications like App Hub.
