Improve build binaries pipeline

Changes made:
- build macOS arm and x86
- rename architecture from amd64 to x86_64, which is much easier to distinct from arm
- remove unnecessary step for self-hosted which is not being used anymore
- create ARTIFACT_NAME env var, so it's much easier to read the code
