Create meaningful telemetry related to `*_runtime` Action Controller attributes

[kaylareopelle]

The db_runtime and view_runtime attributes are generated by Rails and attached to the process_action.action_controller notification.

These attributes sum up the ms spent on DB-related actions and view-related actions respectively.
