Improve autoscroll-iframe-no-scrolling.html 

The behavior in this test differs based on main thread and compositor
thread scrolling. On the compositor thread, only the direct-most hit
scroller is targeted for autoscrolling but the main thread will bubble
up to the first scroller that can consume the scroll. See the
autoscroll-related comment in LayerTreeHostImpl::FindNodeToLatch.

The compositor behavior is the intended one, see
https://crrev.com/c/1743028 which implemented this behavior on both
threads and added a test that was unfortunately removed in
https://crrev.com/c/2111831. The test in this CL covers this case just
as well so we just move it to fast/scrolling to ensure it gets coverage
on both compositor and main threads.

This test ensures that autoscrolling doesn't scroll an iframe that's marked
as unscrollable via `scrolling="no"`. To test manually, fully scroll the blue
inner scroller and use middle click autoscroll (Windows feature) from the
inner blue scroller to scroll downwards until the main window begins to
scroll. This test passes if the iframe that contains the blue scroller
doesn't scroll.
