Implement ExtraTestMacros for all platforms

[mjcarroll]

🦟 Bug fix

Fixes gazebosim/gz-transport#336

Summary

When working on gazebosim/gz-transport#336, I noticed that we don't have the full set of macros for enabling/disabling tests on a per-platform basis. These may not all get used, but it at least completes the set.
