map_each deadlock prevention 
map_each previously was written such that if a chain of mappings fed
each other, a deadlock could occur because while the first one was
mapped, the second callback gets invoked and tries to update the first
value while it's still being held.

This refactor switches from std Mutex to parking_lot, allowing me to
remove a workaround for needing to run drop callbacks in a separate
thread during the drop of a DynamicGuard.

In addition to that change, the lower level `map_generational` calls now
take a DynamicGuard as their parameter. This allows these functions to
drop ownership of the referenced data during the callback.

The map_each implementation takes advantage of this by ensuring that the
guard is dropped before set is invoked, minimizing potential lock overlaps.

With this refactor, some old code of mine with complex validations now works
again.
