## Message

```
gpui: Add bare bones benchmark framework (#58191)

### Summary

Adds the first pass at `#[gpui::bench]`, backed by Criterion, with a new
`BenchAppContext` for GPUI benchmarks.

This ports one editor benchmark to the new setup while keeping the
existing Criterion render benchmarks in place.

### Follow Ups

I eventually want to improve this framework to create custom tracy
profiles that includes additional information such as
- notify count
- entity.update count and time
- event emitted and time for that

I also want to use this to create custom measurements so benches can be
used for
- Frames dropped 
- foreground thread time
- Render time
- etc


This PR is a very small proof of initial concept and I'll continue to
build this infrastructure out so Zed and other gpui apps can become a
lot more resilient to dropping frames and hangs. Plus it will make
improving performance a lot easier as well in the future.
