* wasm: update wabt and binaryen in builder image * wasm: bump ubuntu and llvm * wasm: bump LLVM 13 -> 21, adjust headers * wasm: make docker optional We depend on it in our builds, but if you happen to bring clang (LLVM 21) clang++ (LLVM 21) wasm-ld (LLVM 21) wasm2wat (wabt) wasm-opt (binaryen) node you should be able to build the opa.wasm blob without the docker image.
