Bug 1569672 - Collect use counter denominators in release r=janerik

Use counters are collected in release as of bug 1477433. Per bug 1204994, use counters need to be interpreted relative to CONTENT_DOCUMENTS_DESTROYED and TOP_LEVEL_CONTENT_DOCUMENTS_DESTROYED, so these need to be collected in release, as well.

Also cleans up probe definitions and removes from whitelists.
