[MIRROR] Saves profiler snapshots every 5 minutes (#27875)

* Saves profiler snapshots every 5 minutes (#83467)

## About The Pull Request
As the title says. Each saved snapshot will be named
- `profiler-[TIME IN SECONDS].json`
- `sendmaps-[TIME IN SECONDS].json`

For example, `profiler-0.json`, `profiler-300.json`, `profiler-600.json`
would correspond to a profile at the start of the round, a profile 300
seconds into a round and a profile 600 seconds into a round.

The timings depend on world.time, so it's probably not a good idea to
rely on these timings to stay consistent.

## Why It's Good For The Game
Allows us to track performance of procs over time. Could allow us to
spot any sort of anomalies or performance sinks.
