Add platform-specific BLAS backend configuration and update Linux build dependencies

- Configure BLAS backend per platform: Accelerate for macOS, OpenBLAS for Linux/Windows
- Move blas-src from common dependencies to platform-specific target sections
- Add libopenblas-dev to Linux CI build dependencies for ARM64/x86_64 cross-compilation support
