feat: avm module upgrade for CKM

[AjitPadhi-Microsoft]

Description

This pull request removes three Bicep modules related to AI Foundry resource provisioning and key management. The modules previously managed the deployment and configuration of AI Hub, AI Services, Search Services, and related Azure resources, as well as the handling of secrets in Azure Key Vault. The removal simplifies the codebase and likely reflects a shift to newer, more secure, or standardized deployment patterns.

The most important changes are:

Removal of AI Foundry resource provisioning modules:

• Deleted the ai-foundry.bicep module, which orchestrated the deployment of multiple Azure resources (AI Hub, AI Project, AI Services, Search, Storage, Container Registry, Application Insights) and managed their configuration and interconnections.
• Deleted the ai-foundry-ai-hub.bicep module, responsible for provisioning and configuring the AI Hub resource, including its connections to Cognitive Services and Search, and passing resource keys.

Removal of Key Vault secret management:

• Deleted the ai-foundry-kv-secret-cog-services-key.bicep module, which handled storing Cognitive Services keys as secrets in Azure Key Vault.
