Use head state for exit verification (#4183)

Browse Source 
## Issue Addressed

NA

## Proposed Changes

Similar to #4181 but without the version bump and a more nuanced fix.

Patches the high CPU usage seen after the Capella fork which was caused by processing exits when there are skip slots.

## Additional Info

~~This is an imperfect solution that will cause us to drop some exits at the fork boundary. This is tracked at #4184.~~
