Add a FindPointeeOrNull method to map-util

This adds a new FindPointeeOrNull to map-util to use with maps having smart
pointers as values (like shared_ptr or unique_ptr). The new method returns
a raw pointer to the value contained in in the smart pointer, if the key exits
or nullptr if it doesn't.
