[Java] Add darwin-x64 native runtime support

Cross-SDK Consistency Review ✅This PR adds Intel macOS ( Why no other SDKs need updating: The changes are entirely Java-specific infrastructure:
The Java SDK's native runtime bundling model (using platform classifiers and Maven profiles to ship the Copilot CLI binary) is unique to the JVM ecosystem. The other SDKs (Node.js, Python, Go, .NET, Rust) use different mechanisms to locate the CLI and do not have an equivalent "native bundling" layer that would need a matching No action needed in other SDK implementations.

| The platform detector recognizes the 8 classifiers listed in this ADR. The Maven build binds native packaging only for a host matching an implemented classifier. Linux x64 and ARM64 glibc hosts can opt in with `copilot.native.libc=glibc`, while Windows x64, Windows ARM64, Intel macOS, and Apple Silicon macOS hosts package `win32-x64`, `win32-arm64`, `darwin-x64`, or `darwin-arm64` automatically. The `inprocess` test profile selects the matching implemented classifier automatically on all six hosts. Every path validates the host before downloading or packaging native files. Linux musl and other unsupported hosts build only the OS-neutral placeholder, sources, and Javadoc artifacts unless they explicitly request in-process tests, which fail during host validation. Additional classifier artifacts remain follow-up work. | ||

| Maven Central release and snapshot workflows build each classifier on its matching native host from the same immutable source. The Linux ARM64, Windows x64, Windows ARM64, and macOS jobs each upload only their verified classifier and checksum manifest. The Ubuntu x64 job verifies and attaches all four, builds `linux-x64` with the glibc opt-in, and performs the only Maven deployment. Release signing therefore covers the neutral artifacts and all five classifiers in one deployment. | ||
