Show when impl-side scrolling (aka fast scrolling) has switched on or off and its cause, i.e. the browser couldn't just scroll the textures it had but had to come back to the main thread for additional paint / rasterization work first

More context:

Much as we show records for paints, layouts and composite operations, it would be great if we could have a record that showed that impl-side scrolling has been enabled or, perhaps more crucially, disabled. Again if we can tie this back to the change, JS or CSS, that caused us to have to repaint tile(s) and come off the fast scrolling that would really help developers to see the performance implications of their code.

Chromium and V8 have left the building. Won't fix.
