gpui: Fix dropped frames when scrolling an unfocused window (#61600)

Scroll events are delivered to the window under the pointer even when it
isn't focused, but we cap inactive windows at ~30fps to save energy, so
scrolling an unfocused window visibly drops frames. We now exempt
high-rate input from the cap using the existing `InputRateTracker`: a
trackpad scroll stream lifts it while events are arriving and for one
second after the last burst, then the cap resumes on its own.
