This PR adds a small utility script for the existing `next/trace` converts emitted output into chromium's trace event format (https://docs.google.com/document/d/1CvAClvFfyA5R-PhYUmn5OOQtYMH4h6I0nSsKchNAySU/preview?mode=html#). Converted output can be loaded in a couple of visualizers that understand trace event format.
- `chrome://tracing`
- `https://ui.perfetto.dev/`
Technically it is possible to make generated event format to be compatible to chrome devtool's profiler as well, but that is not dealt with initial implementation.
This is very straightforward, naive conversion between generated trace to the specific format instead of trying to augment existing traces: in result, some of the values are dummy (pid, tid, category). Depends on usecases we can potentially expand & correct later if needed.
Below screenshot is perfetto from `bench/nested-deps`.
