Move event traces to detailed_trace!

[james7132]

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.

This probably shouldn't be merged without #7731 being addressed so we can measure the impact this has on events.

---

Changelog

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

This may have an impact outside of just user-facing events. Since #7713, this also impacts component removal:

When setting up the benchmarks for #8251, I found nearly 5x improvements to event sending. Didn't impact event iteration.

Yikes (or yay?) 5x improvement!
