Austin Clements 35c7234601 runtime: add always-preempt maymorestack hook
This adds a maymorestack hook that forces a preemption at every
possible cooperative preemption point. This would have helped us catch
several recent preemption-related bugs earlier, including #47302,
 #47304, and #47441.

For #48297.
