ci: improve compile and release workflow (#961)

Several improvements to the CI and release workflows:
- Move compilation scripts from scripts/ to workflow files for better maintainability.
- Remove useless scripts related to Docker and shared object generation.
- Compile difftest shared objects only on Ubuntu 20.04 to ensure compatibility with CentOS 7.
- Rename deconfig from dual-xs to xs-dual for better clarity.
