Subject: lib/test_min_heap: update min_heap_callbacks to use default builtin swap
Date: Sun, 20 Oct 2024 12:01:54 +0800

Replace the swp function pointer in the min_heap_callbacks of
test_min_heap with NULL, allowing direct usage of the default builtin swap
implementation.  This modification simplifies the code and improves
performance by removing unnecessary function indirection.
