ci(windows-drivers): LLVM via portable tar.xz + self-provision driver-build

The LLVM NSIS .exe /S silent install HANGS in the headless SYSTEM CI session (stuck >15min after download, blocking the single runner). Switch to the portable clang+llvm-21.1.2-x86_64-pc-windows-msvc.tar.xz (curl + Win11 tar -xf, strip 1) — deterministic, no installer. And make driver-build run the provision script itself (idempotent) so it self-provisions LLVM and never races a separate provision run.
