feat: workaround for
DOMAIN
macro (protocolbuffers#12903)
This is a macro on some (older) versions of GCC, and macOS, and Windows. Sigh. I moved the `#undef` block to a common section. I also took the opportunity to add a regression test for all these macros that need to be `#undef`'d. Part of the work for googleapis/google-cloud-cpp#8125 Closes protocolbuffers#12903 PiperOrigin-RevId: 535649278
