chore: Jest mock consistency

[mdodgelooker]

1. Match the requestAnimationFrame mock in jest setup with that in the core product.
2. Fix paddingSpy in useScrollLock.spec.tsx – not sure why it was working before but the core product wasn't having it.

I removed all existing instances of jest.spyOn(window, 'requestAnimationFrame'), since they are now redundant, except for two in Combobox.spec and Select.spec. Those will take some time to unwind so I want to save them for a follow-up (I created a ticket). In most cases an additional runTimers() call was necessary since the requestAnimationFrame mock uses a setTimeout.
