[WebAssembly] Don't inline -emscripten-cxx-exceptions-allowed functions
Functions specified in `-emscripten-cxx-exceptions-allowed`, which is
set by Emscripten's `EXCEPTION_CATCHING_ALLOWED` setting, can be inlined
in LLVM middle ends before we reach WebAssemblyLowerEmscriptenEHSjLj
pass in the wasm backend and thus don't get transformed for exception
catching.
This fixes the issue by adding `--force-attribute=FUNC_NAME:noinline`
for each function name in `-emscripten-cxx-exceptions-allowed`, which
adds `noinline` attribute to the specified function and thus excludes
the function from inlining candidates in optimization passes.
Fixes the remaining half of
https://github.com/emscripten-core/emscripten/issues/10721.
