[cxx20] Use defaulted comparison operators

[jimporter]

This replaces a few manually-implemented comparison operators with the defaults. I guess these got missed in the big C++20 PR.

Ah ha. Since you're already working on that, I'll just stay out of your way and remove the IPAddress change from this PR.

Ubuntu builds and runs the tests without problems, but Windows 11 Pro fails the test: Utils/NormalizeMountTargetTest.mountTargetsNormalizeCorrectly/3, where GetParam() = ("../..//folder","/folder"). I am unsure if this is due to this PR, since the CI pipeline has been changed to use Windows Server 2025.
After some research I found that it may be to a missing rebase to origin/main, since in main it is fixed, and the normalize target mounts utils function is different due to your commit, so I will be approving this.

Thanks. I've rebased so hopefully everything passes CI now.

It does pass now. Great job!

LGTM!
