Move event traces to detailed_trace! (#7732)

Browse Source 
# Objective
Noticed while writing #7728 that we are using `trace!` logs in our event
functions. This has shown to have significant overhead, even trace level
logs are disabled globally, as seen in #7639.

## Solution
Use the `detailed_trace!` macro introduced in #7639. Also removed the
`event_trace` function that was only used in one location.

---

## Changelog
Changed: Event trace logs are now feature gated behind the
`detailed-trace` feature.
