Add "invoked" metrics to more libraries

[kaylareopelle]

Description

We added a metric that registers whenever the concurrent-ruby instrumentation is invoked to differentiate between times the library is loaded by Rails and times the library is independently used by the customer.

Let's add more "invoked"-type metrics that record the first time some instrumentation is invoked so we can get a better sense of the instrumentation our customers use.

Acceptance Criteria

• Libraries using prepend/chain_instrument methods reviewed for compatibility with record_metric_once
• "invoked"-type metrics are added to the libraries that seem like good candidates
• Angler's metric_names.txt is updated to include the new metrics

Design Consideration/Limitations

We may want to consider dropping the Supportability/Instrumentation/#{LibraryName}/#{Prepend || MethodChaining} metrics in favor of these metrics so that we know when instrumentation is used rather than installed.

Dependencies

Angler updates to allow us to observe the new data

[kaylareopelle]

When we discussed this issue during an estimation session, we decided adding "invoked" metrics would be the most appropriate for instrumented gems that are dependencies of other popular gems.

For these gems, the current installation metrics aren't enough to give us a clear picture of how many users leverage these libraries.
