fix(workflows): update macOS runner references

- Change macOS-latest to macOS-15 in GitHub workflow files
- Refactor flag construction in autoconf and FFmpeg builds for better readability
- Extract flag variables before formatting strings
- Remove macOS deployment target environment variable setting

This change ensures consistent runner environments for macOS builds and improves code maintainability.
