Subject: [PATCH] [build] Add ARM64 support to Linux builds

- Add ubuntu-24.04-arm runner for native ARM64 compilation
- Support building both static and shared libraries for ARM64
- Maintain backwards compatibility with existing x86/x64 builds
- Addresses issue #5051 for ARM64 pre-compiled binaries

Expected output: raylib-X.X-linux_arm64.tar.gz in releases
