Previously, when quickly mounting then unmounting a dropdown, a
traceback was shown. This is because the usePosition hook registered
listeners that were throttled/debounced, which would be called after the
component was already unmounted, causing the crash.
This commit fixes that by making cancelable the debounce timing util
and by introducing a new cancelable timing util: throttleForAnimation.
`debounce` and `throttleForAnimation` could be canceled i.e. when
a component is unmounted.
`throttleForAnimation` is used to replace throttle to avoid the popper's
scroll position not staying perfectly in sync with the page but instead
being slightly jittery, it effectively throttles a given function to the
display's refresh rate.
Also, the `throttle` util is kept unmodified but marked as deprecated.
Its implementation does not properly match its name, and we chose
to leave it as is because some code might already use it.
