[Issue] Greatly improve performance by caching subsequent glob calls

[m2-assistant]

This issue is automatically created based on existing pull request: #33998: Greatly improve performance by caching subsequent glob calls

---

Description (*)

This pull request introduces an in-memory cache for glob system calls. On systems where file I/O is slow (for example Docker for Mac), glob system calls can be quite slow. This pull requests caches the same glob calls and returns a cached result if possible. In my testing this reduced the glob calls on the category listings from ~8K to ~1.6K.
