feat: linux arm64 support & musl detection

## Rationale pact-reference has introduced musl and arm64 based ffi libraries for linux - pact-foundation/pact-reference#416 Tracking Issue - pact-foundation/roadmap#30 ## Issues Resolved fixes pact-foundation#498 fixes pact-foundation#496 fixes pact-foundation#500 fixes pact-foundation#374 fixes pact-foundation#387 ## Backwards Compatibility Linux glibc based hosts take precedence, so if any error occurs during musl detection. I do not anticipate breaking changes for users ## Implementation notes ### .NET notes - Docs - [Uses MSBuild Exec task](https://learn.microsoft.com/en-us/visualstudio/msbuild/exec-task?view=vs-2022) - MSBuild Blog Posts - [Cross-Platform Build Events in .NET Core using MSBuild](https://jeremybytes.blogspot.com/2020/05/cross-platform-build-events-in-net-core.html) - [MSBuild 101: Using the exit code from a command](https://www.creepingcoder.com/2020/06/01/msbuild-101-using-the-exit-code-from-a-command/) - Stack OverFlow - [Set PropertyGroup property to Exec output](https://stackoverflow.com/questions/76583824/set-propertygroup-property-to-exec-output) - .NET runtime musl detection code - https://github.com/dotnet/runtime/blob/a50ba0669353893ca8ade8568b0a7d210b5a425f/src/mono/llvm/llvm-init.proj\#L7 - https://github.com/dotnet/runtime/blob/a50ba0669353893ca8ade8568b0a7d210b5a425f/src/libraries/Common/tests/TestUtilities/System/PlatformDetection.Unix.cs\#L78t ### Conditions for execution musl detection will run if - if linux - if /lib/ld-musl-(x86_64|aarch64).so.1 exists - if ldd bin/sh | grep musl is true (musl lib is loaded, rather than glibc) will continue on error, reverting back to glibc based libaries. ### Supported musl targets should work for multiple musl based distroes if - /lib/ld-musl-(x86_64|aarch64).so.1 exists - ldd is available (available by default in alpine images) Tested on Alpine ARM64 / AMD64. ## Caveats - [.NET does not run under QEMU](https://github.com/dotnet/core/blob/main/release-notes/8.0/supported-os.md#qemu) affecting the ability to test multi-arch from a single system - .NET restore can take a long time when running under containers. - [Workaround](NuGet/Home#13062 (comment)): Set `DOTNET_NUGET_SIGNATURE_VERIFICATION` to `false` ## Compatibility ### Operating System Due to using a shared native library instead of C# for the main Pact logic only certain OSs are supported: | OS | Arch | Support | | ------------ | ----------- | -------------------------------------------------------------------| | Windows | x86 | ❌ No | | Windows | x64 | ✔️ Yes | | Linux (libc) | x86 | ❌ No | | Linux (libc) | x64 | ✔️ Yes | | Linux (musl) | x64 | ✔️ Yes (Tier 2)* | | Linux (libc) | ARM | ✔️ Yes (Tier 3)* | | Linux (musl) | ARM | ✔️ Yes (Tier 3)* | | OSX | x64 | ✔️ Yes | | OSX | ARM (M1/M2) | ✔️ Yes | #### Support - Tier 1 - Established - Full CI/CD support. - Users should not encounter issues - Full reproducible examples running in CI, should be provided by users raising issues - If using musl targets, users should attempt the same test on a libc target (such as debian) - Tier 2 - Recently introduced - Full CI/CD support. - Users may encounter issues - Full reproducible examples running in CI, should be provided by users raising issues - If using musl targets, users should attempt the same test on a libc target (such as debian) - Tier 3 - Recently introduced, No/limited CI/CD support. - Users may encounter issues - Full reproducible examples which can be run by maintainers locally, should be provided by users raising issues
