Deprecate License Compliance Widget Metrics

A follow-up to #373005 (closed).

#373005 (closed) and !111725 (merged) introduced the EE only metrics for the license compliance widget as part of &9876

This issue is to follow the steps in https://docs.gitlab.com/ee/development/service_ping/metrics_lifecycle.html#remove-a-metric to deprecate the original CE/EE metrics introduced in !96538 (merged).

License compliance is a EE/Ultimate feature only, so we need to eventually remove from CE only. This issue is to track the effort in deprecating the CE metrics.

Todo

Also remove:

• counts.users_clicking_license_testing_visiting_external_website
• counts.users_visiting_testing_license_compliance_full_report

Removing CE only metrics:
