## Message

```
perf: Add initial benchmark for markdown element (#59524)

## Summary

This PR adds an initial markdown element renderer benchmark, so we could
later expand this to benchmark search in markdown, and reparsing. This
is important because the agent panel renders a lot of markdown elements,
so I want to use these benchmarks to ensure our markdown element
performance is good, and later expand them to include the agent panel

I added a `bench_util.rs` file that has methods to generate random rust
modules, this will later be used by the editor benchmarks, and is
currently used by the markdown and edit_file_tool benchmarks.

Finally, I made `cx.bench_renderer` also account for ready foreground
tasks and poll them. This more accurately mimics gpui dispatcher. (It's
not perfect, but it's good enough for a benchmark)
