Heejin Ahn 48acac3629 [WebAssembly] Warn on exception spec only when Wasm EH is used ...

Summary:
In D80061 we added warning for exception specifications with types (such
as `throw(int)`), but it was enabled every time the target was wasm,
which means it warned (and ignored) exception specifications even if
wasm EH was not used. This fixes it and we only have the warning when we
enable `-fwasm-exceptions`.
