[Kyle-Ye]

Add GitHub action support for PR pipeline check

eg. for each supported Swift versions (Swift 5.7 5.8 5.9 5.10 6.0) + each supported platforms (macOS/iOS/Linux/...)

Example:

• https://github.com/apple/swift-nio/tree/main/.github/workflows
• https://github.com/apple/swift-mmio/blob/main/.github/workflows/swift.yml
