Subject: [PATCH] bump the hermetic LLVM/clang toolchain pin to 22.1.8

Flip `llvm_version` 20.1.8 -> 22.1.8 (the 22.1.8 distributions were already
registered). This is the toolchain `--config=clang` uses; validated locally that
the hash benchmark builds under it. CI's clang matrix (and macos-26 ASAN) is the
broad validation.
