Fix CI tests

[chfoo]

• The CI tests need to be fixed to use the latest GitHub actions.
• The unit tests and release scripts should be separated into two workflows
• Add aarch64 support

Problems:

• Microsoft/GitHub removes old GitHub runners, action services, and vcpkg tooling. (Reproducible builds aren't going to happen..)
• vcpkg tries to download from overloaded sites (i.e., freedesktop.org)
• Emscripten build: source GitHub repository exceeded its LFS budget
