This is required to make sure we resume the wasm instance when a promise resolves. As a bonus QWasmSuspendResumeControl already implements the JS -> C++ callback mapping, and we can removed the fixed-4 ThunkPool which the current implementation is using. The implementation is straightforward, where the only snag is that cleanup must be done in the finally callback. Implement Promise::all by calling JS Promise.all(). This function returns a new Promise, which we can adopt. Make two changes to the test: - remove throwInThen(): We no longer support propagating JS exceptions from the then() handler to the catch function. (catching a rejected promise still works). As far as I can see this functionality is not used in qtbase. - In finallyWithThen(), change shared_ptr<bool> to plain pointer. This works around a (mysterious) issue where we were not getting the correct value when reading from the shared_ptr.
