memdebug: stop tracking send and recv

- they rarely catch any problems
- we have other ways to test different send/recv problems
- the number of such calls vary much more per invoke than others, making
  memdebugging harder
- reducing the total number of fallible functions per test is good
- they were not used as intended anyway

Closes #20097
