Emergency Profile Dumps (#75924)

## About The Pull Request

Adds some hooks to the MC that detect if something ate a ton of real
time last tick, and reacts by dumping our current profile into a file

It's really frustrating to see a spike in td in our performance logs,
but see no reason in the profile because it's only taken every 5
minutes. This resolves that

I'm throwing this up so mso can give it a look over, not sure if I want
to use defines or configs here, taking suggestions

🆑
server: Adds a system to emergency dump profiles if too much time passes
between ticks
config: Added configs that control how often emergency profiles are
allowed to dump, alongside the threshold for what counts as too much
time between ticks
