perf/core: update min_heap_callbacks to use default builtin swap

Browse Source 
After introducing the default builtin swap implementation, update the
min_heap_callbacks to replace the swp function pointer with NULL.  This
change allows the min heap to directly utilize the builtin swap,
simplifying the code.
