Use direct downloads for ARM64 Windows dependencies in CI

GitHub Actions ARM64 runners don't support Appx module. Download and install
all dependencies directly from official sources with proper ARM64 binaries:
- CMake 3.30.5 ARM64
- Ninja build system
- Python 3.13.1 ARM64
- Ruby 3.3.6 ARM64
- Strawberry Perl 5.40.0
- LLVM 19.1.4 ARM64
