Christopher Friedt bd83df1552 libc: minimal: add qsort to the minimal libc 
This change implements qsort() for the minimal libc via Heapsort.

Heapsort time complexity is O(n log(n)) in the best, average,
and worst cases. It is O(1) in space complexity (i.e. sorts
in-place) and is iterative rather than recursive. Heapsort is
not stable (i.e. does not preserve order of identical elements).

On cortex-m0, this implementation occupies ~240 bytes.

Fixes #28896
