Add tests for stacktrace map lookup and delete:
1. use bpf_map_lookup_and_delete_elem to lookup and delete the target
stack_id,
2. lookup the deleted stack_id again to double check.

selftests/bpf: Refactor stacktrace_map case with skeleton2025-09-25T23:17:14ZTao Chenchen.dylane@linux.dev2025-09-25T17:50:29Zurn:sha1:363b17e273f0929ba7791231a0bbb5424204d93a
The loading method of the stacktrace_map test case looks too outdated,
refactor it with skeleton, and we can use global variable feature in
the next patch.
