Add a musl/LLVM Docker build environment for compiling portable Linux
binaries that work on both musl and glibc systems, along with a minimal
PHP Docker image for testing. Add CI workflows to build and publish
these images to ghcr.io. Update test and build scripts to use the new
Docker-based environment, and remove SKIPIF guards from tests since the
extension is always present and doing otherwise would mask extension
loading failures.
Wire up PHP 8.1 Linux matrix jobs (debug + release-zts) via Docker image
SHA entries and Justfile targets. Update Windows CI job from PHP 8.0 to 8.1.
No C source changes required for 8.1 compatibility.

Replace the old Azure Pipelines + Appveyor setup with GitHub Actions:
- Add .github/workflows/tests.yml with Linux (matrix) and Windows jobs
- Add .github/scripts/build-and-test.sh (shared build+test script)
- Add .github/scripts/update-docker-shas.sh (Docker image SHA lockfile updater)
- Add .github/docker-image-shas.yml (pinned OCI index digests for Linux jobs)
- Add Justfile for local test targets mirroring CI
- Add unrar_update.md documenting the unrar update process
- Remove azure-pipelines.yml, azure-template.yml, appveyor.yml, appveyor.bat,
test_funcs.sh
