Improvements for Perforce tests

Hi,

this is the second version of my patch series that improves Perforce tests a bit. As with the first version, the main intent is to mark all tests as leak free. The other two patches polish the Perforce tests such that they work on my machine, which has a more recent version of Perforce than what we have been testing with in CI.

As discussed, despite these patches I consider Perforce to be basically unmaintained, and my patches do not change that. But given that I don't think we can rip out git-p4(1) just so without any kind of announcement up front, I still think that these patches are worth it to help my own cause, namely plugging all memory leaks hit by tests in Git.

Changes compared to v1:

- Fix some typos.

- Add in-code comments explaining what the compatibility case statements are about.

Thanks!

Patrick

@@ Commit message
Update our Perforce version from r21.2 to r23.2. Note that the updated version is not the newest version. Instead, it is the last version where the way that Perforce is being distributed remains the same as in r21.2.
- Newer releases stopped distributing p4 and p4d executablesas well as the
- macOS archives directly and would thus require more work.
