Use clang-18 from apt.llvm.org for the wasm build on 22.04 runners

clang-15 got past the C23 [[noreturn]] error but still fails compiling
sqlite-wasm-rs for wasm32: its stdint.h falls through to host glibc headers
(bits/libc-header-start.h not found). clang-18 handles wasm32 as freestanding
and compiles it (it is what ubuntu-24.04 uses). 22.04's repos stop at clang-15,
so install 18 from apt.llvm.org. Runners stay on 22.04 to keep the glibc floor.
