Add GDPR, COPPA, and LMT anonymizations to activity control metrics

[bretg]

PBS-Java implemented a feature where GDPR, COPPA, and LMT anonymizations are tracked using the metrics in #2591 . These are not net-new metrics, but rather, bringing currently siloed anonymizations into existing metrics to get the global view.

1. whenever PBS removes first party data for COPPA, LMT, and GDPR, log these metrics:

   • requests.activity.transmitUfpd.disallowed.count
   • accounts.ACCOUNT.activity.transmitUfpd.disallowed.count - at 'verbose' metric level
   • adapter.ADAPTER.activity.transmitUfpd.disallowed.count

2. whenever PBS removes EIDs for COPPA, LMT, and GDPR, log these metrics:

   • requests.activity.transmitEids.disallowed.count
   • accounts.ACCOUNT.activity.transmitEids.disallowed.count - at 'verbose' metric level
   • adapter.ADAPTER.activity.transmitEids.disallowed.count

3. whenever PBS rounds off the IP address for COPPA, LMT, and GDPR, log these metrics:

   • requests.activity.transmitPreciseGeo.disallowed.count
   • accounts.ACCOUNT.activity.transmitPreciseGeo.disallowed.count - at 'verbose' metric level
   • adapter.ADAPTER.activity.transmitPreciseGeo.disallowed.count

4. whenever PBS cancels an auction for GDPR, log these metrics:

   • requests.activity.fetchBids.disallowed.count
   • accounts.ACCOUNT.activity.fetchBids.disallowed.count - at 'verbose' metric level
   • adapter.ADAPTER.activity.fetchBids.disallowed.count
