Verbs subsystem (#20333)

What it says on the can; now we can better compensate for processing
spikes by queueing and accounting for verb times (assuming we actually
use this framework to invoke the bulk of them). I have added its use to
some of them, more can be ported as time goes on, eventually everything
but the most trivial ones should go through this.

No player facing changes. Hopefully.

Praise be the omnissiah.
