Add MCP Support to OME

This OEP introduces native support for the Model Context Protocol (MCP) in OME through MCPServer and MCPGateway CRDs that enable Large Language Models to integrate with external tools and services. MCP is an open protocol developed by Anthropic that standardizes the interface between LLMs and external systems, allowing models to perform actions like database queries, file operations, API calls, and infrastructure management in a secure and controlled manner.
