wasm: add macro for for emscritpen::async()
emscritpen:async() needs to be passed to embind exported
functions, if that function might suspend, and if JSPI
is enabled (and only if JSPI is enabled):
emscripten::function("fn", &fn, emscritpen:async());
Add QT_WASM_EMSCRIPTEN_ASYNC macro which evaluates
to ",emscritpen::async()" (note comma) if JSPI is enabled,
and to nothing if not.
emscripten::function("fn", &fn QT_WASM_EMSCRIPTEN_ASYNC);
This way we can configure Qt for either JSPI and non-jspi
builds. Incidentally the emscritpen::async() requirement
makes JSPI a Qt configure time feature, instead of an
app link time feature like for the current ASYNCIFY (1)
support.
