Add support for Azure Redis Cache AccessPolicy and AccessPolicyAssignment resources

[Copilot]

This PR adds support for Azure Redis Cache AccessPolicy and AccessPolicyAssignment resources, enabling users to manage fine-grained access control for Redis instances through Azure Service Operator.

Changes Made

New Resources Added:

• RedisAccessPolicy - Defines custom access policies with specific Redis command permissions
• RedisAccessPolicyAssignment - Assigns access policies to users or service principals via Azure AD object IDs

Implementation Details:

• Added Microsoft.Cache API version 2024-11-01 (stable) to azure-arm.yaml
• Generated complete Kubernetes CRDs and Go type definitions for both resources
• Updated Redis extension to use the new v1api20241101 hub version
• Fixed kustomize compatibility issues for proper CRD generation

Testing & Samples:

• Created comprehensive integration tests following existing Redis test patterns
• Added sample YAML files demonstrating usage of both new resources
• Included complete sample set for v1api20241101 Redis resources

Usage Example

# Create a custom access policy
apiVersion: cache.azure.com/v1api20241101
kind: RedisAccessPolicy
metadata:
  name: custom-policy
spec:
  owner:
    name: my-redis-cache
  type: custom
  permissions: "+get +set +del"

---
# Assign the policy to a user
apiVersion: cache.azure.com/v1api20241101
kind: RedisAccessPolicyAssignment
metadata:
  name: user-assignment
spec:
  owner:
    name: my-redis-cache
  accessPolicyName: custom-policy
  objectId: "12345678-1234-1234-1234-123456789012"
  objectIdAlias: "developer-user"

This enables users to implement Redis RBAC (Role-Based Access Control) patterns by creating policies with specific command permissions and assigning them to different users or applications based on their access requirements.

Fixes #4829.
