This commit:
- adds a "delay" parameter to the `draggable_hook_builder`, waiting for
that delay on pointer down events before triggering the drag sequence
(making it possible to use "long mousedown" events);
- changes the event detection in `draggable_hook_builder` to listen
for pointer events instead of mouse events, effectively supporting the
drag and drop feature on touch devices;
- adapts the test helpers (with some refactors to `triggerEvent` and
other utility functions) to make them use pointer events instead for
drags and drops;
- adapts the tour utils to use a tone-downed version of the refactored
test utils `dragAndDrop` function;
- also changes events in list view which does not yet uses the draggable
hook, but should still work with the same helpers in tests.
