Remove tooltips on scroll wheel events (zed-industries#10069)

This fixes zed-industries#9928 by invalidating the tooltip on mouse scroll.

I think _ideally_ we'd have a solution that only invalidates it if,
after mouse scroll, we're not hovering over the element. But I tried
that (by essentially duplicating the code for `MouseMoveEvent` but that
lead to some inconsistencies. I think we don't redraw when we finish
scrolling.

This now behaves exactly like tooltips in Chrome: invalidate on scroll,
move mouse again to trigger the tooltip.

It also behaves like the hover tooltips in the editor.
