Rename qPromiseAll() helper to QtPromise::all()

For consistency with other helpers, deprecate `qPromiseAll()` in favor of `QtPromise::all()`.

+QtPromise::all(Sequence<QPromise<T>> promises) -> QPromise<QVector<T>>
+QtPromise::all(Sequence<QPromise<void>> promises) -> QPromise<void>
+```
+
+Returns a `QPromise<QVector<T>>` (or `QPromise<void>`) that fulfills when **all** `promises` of (the same) type `T` have been fulfilled. The `output` value is a vector containing all the values of `promises`, in the same order, i.e., at the respective positions to the original sequence, regardless of completion order.
+
+If any of the given `promises` fail, `output` immediately rejects with the error of the promise that rejected, whether or not the other promises are resolved.
+
+`Sequence` is any STL compatible container (eg. `QVector`, `QList`, `std::vector`, etc.)
+
+```cpp
+QVector<QPromise<QByteArray> > promises{
+    download(QUrl("http://a...")),
+    download(QUrl("http://b...")),
+    download(QUrl("http://c..."))
+};
+
+auto output = QtPromise::all(promises);
+
+// output type: QPromise<QVector<QByteArray>>
+output.then([](const QVector<QByteArray>& res) {
+    // {...}
