[core] make getversion() aware of arm64 architecture

"arm64" has been selected as it is more widespread than the Linux-only
"aarch64" name. Only time will tell if this choice was good.

This commit also flatten the #ifdef/#endif architecture selection and
clarify the possible arches on Windows or macOS/Linux.
