[RESEND PATCH v5 12/16] lib min_heap: Rename min_heapify() to min_heap_sift_down()

[Kuan-Wei Chiu <visitorckw@gmail.com>]

After adding min_heap_sift_up(), the naming convention has been
adjusted to maintain consistency with the min_heap_sift_up().
Consequently, min_heapify() has been renamed to min_heap_sift_down().
