[DevTools] Enable pointEvents while scrolling (facebook#30560)

[`react-window` disables `pointerEvents` while scrolling meaning you
can't click anything while
scrolling.](bvaughn/react-window#128).

This means that the first click when you stop the scroll with inertial
scrolling doesn't get registered. This is suuuper annoying. This might
make sense when you click to stop on a more intentional UI but it
doesn't makes sense in a list like this because we eagerly click things
even on mousedown.

This PR just override that to re-enable pointer events.

Supposedly this is done for performance but that might be outdated
knowledge. I haven't observed any difference so far.

If we discover that it's a perf problem, there's another technique we
can use where we call `ownerDocument.elementFromPoint(e.pageX, e.pageY)`
and then dispatch the event against that element. But let's try the
simplest approach first?
