While we were doing some tracing for Rust memory issues, we noticed that
the builds became slower and slower. Turns out we did store the macOS
`.trace` dirs within the auto content directory of the Tailwind CSS
instance we were profiling and that _some of the files were massive
binary files that we were now scanning_.
Here's the anatomy of a single trace:

Note that the biggest binary file is a `.oa` but I've also added
`.storedata` and `.symbolsarchive` as binary extensions to this PR.
