Azure Monitor: Added Microsoft.Cdn/profiles to supported namespace list (#42745)

* Added Microsoft.Cdn/profiles to Azure Monitor Plugin

Microsoft.Cdn/profiles is the Azure Front Door Standard/Premium resource which is not present in the supported namespaces. I would like to use this with Grafana.

* Azure Monitor: Added CDN WAF namespace

Added Microsoft.Cdn/cdnwebapplicationfirewallpolicies
Ensured both Microsoft.Cdn/cdnwebapplicationfirewallpolicies and Microsoft.Cdn/profiles are available in all azure clouds
